Me too :-)

Agreed.

I have done some work on a different app with QML, to learn more about it.
I am impressed as well, but I still have to find good solutions for a lot
of problems (e.g. file I/O, dbus integration, ...) .
But I'm sharing your view, QML is definitely good enough and with the
Ubuntu toolkit, my major objection (no widgets) has gone as well.

I also looked at PySide. Python is, and will continue to be, my

Yes, PySide is dead, I had seen that as well. PyQt however seems still
alive...

That looks really awesome! Great work!
I'm very much looking forward to continuing with that version.

Great work! Let's do this :-)
I do have a question though: have you ever looked into CoffeeScript? [1]
I have started to use it for my other ubuntu app and I think it might be
good. Feels at least a little like Python (if used in the right way...)


Cheers,
