Thanks for answers,
In fact i work on the thee plarforms at the same time (Windows, Linux, OSX) with a big workspace (200+ projects). This is why we chose codeblocks on the first place.
On OSX Codeblocks is really slow (in all aspects, even typing and search in files) but it allows us to build our project, most implementations are done in linux and windows. I can understand that if there is only one developper on its free time no miracle can happen (i don't blame anyone). Still, I was hoping that the new version and the new wx widget would improve the Codeblocks experience on OSX, so it would be great if that happens
