I would be very pleased if you would consider including some more libraries in the official release.
For me it would save a lot of efforts if some of these Hardware Abstraction Libraries could be included. Especially the LED, Button and Keypad libraries.
Also the Timed Action Library, for all those 'I want multiple loops' requests. As well as the Finite State Machine Library.
Well now... Sorry for this selfpromotionishthingy.
