Hi Yordan,

While writing my presentation I found a few slight issues that we need
to address.

  1. Need to show the task in the info window when hovering over the CPU
plot between events, but not idle

OK, I will tray implementing this.


  2. Is there a way to do a quick zoom out. When I zoom in with a lot of
     data, I find that it's quite slow to zoom back out to the original
     screen.

Yes, this is trivial. We just have to find a way to make it intuitive.
Maybe adding another button?


  3. We need a "File exists, do you want to overwrite" type dialog box
     when saving a session over a file that already exists.

Hmm, I thought that it asks before overwriting. I will check this again.


  4. When restoring a session, the full path of the file being loaded
     should be shown. I noticed this because I was loading a trace.dat
     file from a different directory, and I wasn't sure which file it
     found, as I have several trace.dat files.

The full path of the loaded file is shown as part of the name of the window. It will be "KernelShark(/some/path/somefile.dat)"


  5. I noticed a glitch when loading a session with both the A and B
     markers are set here only one marker was shown in the list view.
     I can put the session and trace.dat file someplace that you can
     test this if you want.


There is some regression in the import/export session code. I also noticed some problems there. Will do a careful look.

Thanks a lot for reporting all this issues!
Looking forward to see your talk.

cheers,
Yordan


But so far it looks great! Tomorrow I'll be presenting my talk at 11am
your time. It will hopefully be live streamed if they don't have the
issues that they had at Embedded Recipes. I'll email the list the link
when I have it.
