@Rasch: Making the text markable and multiple selection has already been asked for in this thread. The latter one has a good chance to be implemented in the contest release.
About the tab thing: This would only make sense if all elements would somehow react on the mouse, but that's currently only the case for buttons and editboxes (of course). This would also require a system that makes one window "the" active window, which currently isn't the case.
Personally, I only use tab to switch between different editboxes while filling out a form (like name and password). I could make a "tab event" or "key event" for editboxes so you can do that by yourself.


@Helghast: It's going to be released soon when the contest begins. I guess in one week you can download it.
