# FIXME List:
# * Problems with flickering related to ERASE_BACKGROUND
#     and the splitters. Might be a problem with this 2.5 beta...?
#     UPDATE: can't see on 2.5.2 GTK - maybe just a faster machine :)
# * Demo Code menu?
# * Annoying switching between tabs and resulting flicker
#     how to replace a page in the notebook without deleting/adding?
#     Where is SetPage!? tried freeze...tried reparent of dummy panel....
#     AG: It looks like this issue is fixed by Freeze()ing and Thaw()ing the
#         main frame and not the notebook

# TODO List:
# * UI design more professional (is the new version more professional?)
# * save file positions (new field in demoModules) (@ LoadDemoSource)
# * Update main overview

# * Why don't we move _treeList into a separate module
