(this is binary of theide, u++ sources are in normal trunk).
Cocoa theide is now more usable than X11 variant, but a lot of things needs to developed/fixed. Brief list of issues is in CtrlCore/cocotodo.txt.
I appreciate any inputs.
There are somne issues with mac keyboard differences: K_CTRL is mapped to Command key (e.g. means Ctrl+C, Ctrl+V works as expected), K_ALT to Control key. (OSX U++ also adds K_OPTION). As Command+Tab is unavailable in OSX (consumed by task switcher), cycling of files is mapped to Option+Tab.
