Hello people.
I've been kindly invited by Michael Natterer to discuss the recent issues
I filed in Gimp buzilla (see bug #680584). I am a happy Gentoo user since
2004. I'm only using safe CFLAGS (tell me if you think they're relevant to
this discussion, I'll provide them). My machine is a Core i3 running GCC
4.5.3.
Globally I must confess I'm pretty disappointed with important interface
redesigns in version 2.8. I'm no hardcore Gimp artist nor user but there
are a couple of features that now make Gimp rather stand in my way than
help me. These are mostly usability issues of features that once were
straightforward and now are less to not intuitive at all, or even counter
productive.
I've really tried my best to adapt but in the end I can't. I'm also of the
opinion the software must adapt to people and not the contrary. But as
I've been an enchanted Gimp user for years I decided to swallow my pride
and give this new version a try.
Fail.
Here's why.
GIMP 2.8 annoyances
I. "Two-faced" sliders
1. Behaviour
2. Usability
3. Relevance
4. Impact upon shortcuts
II. Brush dynamics
1. Usability and friendliness
2. Relevance
III. Tablet-specific issues and regressions
1. Pen/Eraser consistency
2. Unintentional floating
3. Dialogs and menus
IV. Conclusions

I.1. Two-faced sliders, behaviour
There's no more brushes of various sizes in this new version, I'm okay
with that. It just means the size sliders are now critical components of
the interface. Fair enough.
However the behaviour of those sliders has [almost] nothing to do with
ordinary sliders, hence I dubbed them "two-faced" sliders. It actually
took me quite a while to figure out what was going on when I saw my
current brush wizz to an unbelievable size!
Nothing clearly advertises the behaviour of Gimp sliders. With this
version, you *must* be careful to the proper half you're picking, which is
*not* how sliders work in general. So if your sliders break the usual
behaviour, make it obvious.
My own suggestion: don't make such use of sliders!
Gimp 2.6 coarse and fine tuning was almost right (progressively increasing
rate). It just needed to be not too fast in the end.
I.2. Two-faced sliders, usability
I have nothing against coarse and fine grain tuning for brush sizes but the
sizes I generally work with (i.e. 1-100px) (and I'm sure I'm not the only
one) confine the usable range to 1-10% of the whole slider area!
I don't care of sizes such as 1000 pixels (which is less than the max.
size when the cursor is slid to the far right) when I can only aim into an
area as tiny as 10-20 pixels to tweak my brushes between 1 and 100 pixels.
Note that the work range even go beyond the right limit of a slider, i.e.
to the opposite side of the screen! (I don't see that as an inconvenient
though.)
Another negative impact I see with those sliders is how accurate one needs
to aim with a pen. As per my own experience, I've never missed a
coarse/fine tuning with the mouse, which makes sliders more appropriate
with mice. Does that mean I must use all of my three input devices,
keyboard, mouse and tablet? God, I hope not! With Gimp 2.6 I could at
least put my mouse aside; managing my Xfce desktop with a pen has proved
less disturbing than manipulating Gimp!
I.3. Two-faced sliders, relevance
For example, I've placed my brushes tools to the left of the screen
(1920x1080). When the size slider is dragged to its right edge, my brush
size is about 1000 pixels. But I can also drag it to the right side of my
screen, which gives me a brush about 8900 pixels wide! Of course, Gimp
starts to lag when I paint at such sizes... I never work with canvas that
big. Not sure everyone else does.
In short sliders are non-practical for very small brush sizes.
Also not the use of decimals. What is the point of decimals when:
a. they're only useful with small sizes,
b. small sizes are confined in the lowest 10-20% of a slider's range ?
I.4. "Two-faced" sliders, Impact upon shortcuts
Notwithstanding the fact that sliders complicate the overall usage of the
interface, they also drastically multiply the number of shortcuts. With
Gimp 2.6 only two shortcuts sufficed: «up» and «down». Now it's
«up», «up skip», «down» and «down skip». Add that the mouse has
its own increment style, which makes six "shotcuts" for just *one* slider!
And my tablet has only 4 (four!) buttons. What should I do? Should I vote
for size? Opacity?
Mind you, there are sliders for
. brush size
. brush opacity
. layer opacity
. brush aspect ratio
. brush angle
. brush rate
. brush flow
. brush spacing
. scattering amount
. smoothing amount
. smoothing weight
and I've inventoried only the most obvious ones. That would make
approximately 44 -- forty-four! 8-o -- shortcuts to a minimum! C'mon guys!
Is that really what you had in mind? Of course I don't want one shortcut
for each of these features but you can't deny you've divided by a factor 2
the possibilities of tablets, keyboards...
I loved Gimp 2.6 up/down buttons. They were a nightmare to use when the
repetition rate was too high but at least you could make your way through
easily.
II.1. Brush dynamics, usability and friendliness
I have no idea why, all of the brush dynamics in Gimp 2.8 cannot be
changed. I need to create a custom dynamics and use it whenever I need to
change the dynamics parameters... Wait a minute: so you're now telling us
*all* we need to do is clone a dynamics "preset" and edit that? And we
just need to delete it when done? Why not reboot the computer twice while
we're at inventing oddities?
You cannot be serious?
II.2. Brush dynamics, relevance
So if we have to clone a dynamics set each time we want to check this or
that parameter, what's the point of
1. making that many dynamics sets,
2. making them *all* read-only?
If you had wanted to complicate Gimp and give the feeling it stands in our
way, well, goal reached.
Add that I had to figure out how to create a new dynamics set. Okay, I
took much less time than I needed to figure out how sliders work but it's
just one more obstacle to Gimp usage being straightforward and intuitive.
My suggestion: make *all* of those dynamics preset editable! Just like
Gimp 2.6. And I honestly don't give a damn whether they store my
modifications or forget them as soon as I quit Gimp. I just don't want to
battle each time I need to get around a new feature that's been placed in
my way!
III.1. Tablet-specifics, Pen/Eraser consistency
First thing I noticed in 2.8 is that I now need to select the eraser tool
when I flip my pen to use the eraser. I didn't have to do that in 2.6.
Also, and it pisses me off hard, believe me, the eraser and pen share the
same size. So whenever I flip my pen and use the eraser, change the brush
size, flip it again, have to restore the paint size again...! This is
getting obnoxious, really.
III.2. Tablet-specifics, Unintentional floating
A bug, probably. I don't have that issue with the mouse: many times, as I
select an item from a drop down list (brush dynamics, brush...) using my
tablet's stylus (paint or eraser tool) the list becomes a floating window
and I need to dock it again... sighs.
III.3. Tablet-specifics, dialogs and menus
A bug, which was present in 2.6 and is still not totally fixed in 2.8:
using menus with the stylus sometimes (in 2.6 it happened all the time)
makes dialogs unusable. They need to be used with either the mouse or
keyboard. The best work around is to close with the ESC key and do it
again... or use the keyboard/mouse... In short it depends how fast or slow
I tap the menu item with the pen. I happened to be able to use dialogs
with the pen if I was *extremely* fast to tap.
This is one more argument in favour of the keyboard/mouse/tablet triplet.
I just wish I had one more arm for ten fingers definitely seem not enough
with everything I exposed.
IV. Conclusions
Well, there's a good side anyway. These annoyances made me want to dig
MyPaint deeper and use it, another great open source paint software.
I find it even more sad, however, because Gimp has been my tool of choice
so far whenever I wanted to paint. Now it stands more in my way than it
used to help. I hope it will change.
To summarize my suggestions:
1. Make sliders behave like sliders the way we all know.
2. Restore Gimp 2.6 progressive rate (using up/down controls, why not).
3. Make *all* of the brush dynamics editable, even not remembering custom
settings, it's not that important. To me at least. You might need to
ask for other people feedback.
4. Stop forcing users to run through additional steps to restore the
behaviours they once loved, e.g. create/clone dynamics to have editable
dynamics: all we want is editable dynamics. Period.
Please bear with me, it took me 2 hours and a half to write this. I
wouldn't have bothered at all if I weren't *really* annoyed.
Thanks a lot in advance,
Vince C.
