Yay! You/Cacko isn't dead!!
I'm so excited to hear there's going to be a next version!
Anyway...
My wishlist as i can remember at the moment (some repeats from others):
-The KO/PI PIM applications that everyone is raving about. As someone above mentioned, i hate to have redundant programs installed, and the PIM stuff installed just doesn't do it for me
-Fix (if at all possible) the bug with the screen brightness/ musicplayer blank screen, so that other n00bies don't run into the same weird problems i had (the screen would blank for about 30 seconds at a time, and then come back on, only to go blank again as soon as a button or screen event occurred)
-Consolidate the media apps. I can't recall which does what, but i know that only one player 'sees' directories, while the other player can't play OGGs. The OGGless player is the one that my Zaurus Remote Control activates. Combining all the functionality into one would be really neat, if possible. I also like the suggestion that the buttons on the RC be remapped (stupid stop button!), but i think that's probably beyond the scope of this project.
-Does anyone use Netfront? I was trying to figure out why both Opera and Netfront are installed. Maybe we only need one browser (unless there's an orthogonal feature set, like with the media apps). Just a thought
-Finally, for some reason prboom doesn't seem to work right from the menu (but fine with some fudging from the shell). I read somewhere this is only a problem with Cacko. A rather minor thing, of course.

Anyway, i'm really excited to hear you're working on a new release. Thank you!
