Some items that just came to my mind:
- replace term 'visual' by 'symbol'.
- add a 'Remove' button to get rid one or many marked classes
- Make the frame a dialog window.
- add hot-keys to the buttons
- make the widgets resize with the window size

I propose to skip the range generation for release 0.2.0.
You can make the button ivisible for the release and afterwards
start implementation of this quite sophisticated feature.

yeah, those need to be fixed and some missing to be added for 0.2.0.

good idea for 0.2.0.


Finally, we should remove the critical bugs listed in the thuban
bug tracker - of course :-)
