Development is on hold for a little while, until I get my computer sorted out
The first public beta, when released, will be in a similar state to the current private beta. That is, it will work, but wont have much in the way of 'features'. Icons are the same as the current format plus an 8bit alpha mask image and the backgrounds can be 16 or 24bit, you will be able to scroll the icons and load them by tapping on one. Anything intended to be added after that will be a while longer.
But you will all have to wait at least a couple of weeks fir the first beta I'm afraid.
