Downloaded to my mytouch and so far i'm liking it.
Couple of suggestions
1. For the option on the launch bar to bring up the phone, can you make it bring up the dialer and not the recent call list? kinda like the Hero
2. Now, when you press the menu button, the app tray pops up. I'd prefer if the normal menu would pop up. The one that has the option to change wallpaper, notifications, etc.
3. if there is a way, when trashing an icon, to make the whole bottom bar the trash, not just the bottom left corner.
4. the possibility to skin the launcher. (edit: i see in the original post that you said your working on this)
bugs i've noticed:
-when # of visible screens is set to 3 and default desktop is set to 1, you can not scroll all the way through. if you swipe right or left one time thats all that you can do. it doesn't allow you to swipe again to get to the home screen. edit: i forgot to mention that its when its in stretch mode and it doesn't work on any configuration (ie default desktop 1,2,etc). it works fine on cube
-when changing an option that require the restart of the launcher, it pops up the last used application such as sms or gmail.
