Hi everybody,
I'm really sorry but (as you may have already noticed) I really have no time to work on this subject anymore, at least for the upcoming months.
Some days after starting this thread I sent a small patch to eranif, part of which got included in wxAUI tree. Sadly that was all I could do. I planned to join 280Z28's attempt to merge wxAUI and wxFlatNotebook, but that project seems to be dead (well, I'm not sure, it's some time since I last checked its SVN repository). Maybe in the future I'll find some time to work on this subject, but for now it's impossible. I hope that this "proposal" didn't stop any other project and, if, so, pleas accept my excuses.
Best regards
Olorin
