Just to inform, I am working on a 0.6.2.5 simply because I like the simplicity of this system (and my lazyness to learn yet another thing like Siena).
What I am doing:
1) integrate a new html editor : Redactor from http://imperavi.com/
2) introduce a new pfs (called myfiles)
3) And most important HTML 5 (fully: Bootstrap responsive)
The last point gives my headaces because, OH MY GOD, why is there so much HTML in the php files, what should be in the TPL.
So I am moving all html stuff into the tpl, so i can really make the skin independant from the code.
I still find the Genoa kick ass, and i have made it 'my' system now, because it is discontinued (which was understandable, but a mistake in my eyes)
