MonoKit originally started out as a library in a similar vein to MonoTouch.Dialog. It has some elements of this, but has diverged to include other features as well. It is still in progress :)
A TableViewSource to build table views using a binding framework and "templating cells". This is probably about 50% done.
A CQRS / Event Sourcing framework. This is about 75% - quite functional just missing some extras.
A port of ViewDeck (https://github.com/Inferis/ViewDeck). This is complete and functional. There is a sample in the samples folder that shows how to use this. Also the original ViewDeck project has some good documentation as well.
A Panorama View.
A port of AwesomeMenu (https://github.com/levey/AwesomeMenu).
I look forward to any comments you might have.
