What about:
- left mouse click = zoom in
- middle mouse drag = move around
- right mouse click = zoom out
or use shift-left and have a little context menu with right

Hmm... a pretty weird preview comes to my mind. It might be difficult to
implement though. The preview is not separeted into before and after
views but shows one part of the image. There is an invisible borderline
between before and after so that there is a transition from before- to
after-image. The interesting thing is: This border-line can be rotated.
You therefore have the option to have a preview like above or one
separated top-bottom or diagonal - any way you like.

Definitely. It should be toggleable from the preview widget itself.
Also, the plugin has to choose in which mode to start. There are
plugins for which a tiny preview is useless (e.g. global operations like
brightness and contrast.)

The preview widget also needs an option to toggle between automatic or
manual preview update since there are effects which take very long to
compute - even for a small preview.
Hmmm... what about embedding a real image inside the preview?

I want resizeable (rectangular) selections!

- Should allow more sophisticated text layout (e.g. changing fonts and
styles for parts of the text, alignment for each lines, tabulators)
Bye, Tino.
