Hi,
I told you, cpasjuste is currently working on a simple and clear launcher, using skeezix libpnd to work with PXML.
cpasjuste just posted a small sneak preview of the menu, you can see how PXML works (showing icons in categories, preview pictures, etc.).
skeezix libpnd is already pretty advanced. Together with vimacs, he made it possible for EVERY dev to easily use PXML and therefore, automatically add games and programs into the right categories as soon as you put an SD card into the slot!
We will show a video with that feature included into the matchbox UI as well soon!
