I've been toying around with an idea for code-only GUI layout library for MonoTouch which I've called XibFree. It's heavily inspired by Android's layout engine which I think is quite good.
It's no where near ready for use, but thought I'd put up some sample code for comment/feedback. Check it out here: (Ignore the terrible screen shots - they're straight from my test app and simply to have something to reference against the code.).
So, would you use this? Is it worth pursuing? Is there something else like this already out there?
Of course suggestions for improvements also welcome.
