I totally see your points there :)

I've not personally used anything quite so low level as xlib (stop
laughing all those people who don't consider xlib low level!!!).

I was just trying to push my own wants on you seeing as I'm unlikely to
find time to do such a project anytime soon :o)

Good luck.

PS I'd be interesting in potentially using your app if it's o/s, so
please let me know how you get on.
