Finally got time to try it, sorry for the delay.
It looks mostly very good to me.

It's a bit hard to make an opinion (I often see the 'Not yet implemented' message

) but what is implemented so far looks good.
Also I'd have a couple bugs to report if you want, but given it's still a very early version they might just be corrected in the next version..
Speaking of which; do you have an idea when you might release a new version?
