It involves rewriting all of the menus in a N900 happy way. I started this too for another app but got so bogged down in it,and there so little info out there on it that I gave up. Would love to have another go, but been made redundant and now trying to run 2 businesses just to eat. lol.
Last time I asked for info, I was told hildonizing is the old way, and it's all changed now... been a while so would have to refresh my memory...
