RC5 is great the way it is, except for one gripe that I have:
Either via a config option somewhere, or a replacement package, remove the right click after 500ms 'feature' from tslib. It's VERY annoying when dragging windows around, etc. I would much prefer to run an app such as xmonobut or similar to allow middle/right-click via a keyboard press + tap with stylus.
Other than that, keep up the great work!
