I've been sparingly, though I wish I could spend more time, working on making "nice fonts", ttf and others, work with xcb ( https://github.com/venam/fonts-for-xcb ). I kinda reached the stage where I have to link everything together in a library-usable way.
At the same time I'm going to document the process plus add a bunch of approachable documents on some X windowing system related concepts that are really lacking in online content.

The big plan is to join all that back with code examples, such as writing a compositor, and then finally, with the new knowledge, continue the refactoring of 2bwm.
