I think the wallpaper issue might be related to the fact that the current wallpaper is stored as a png located at '/data/system/user/<USER_NUMBER>/wallpaper'... Is there some way we could have different wallpapers for each ROM? Maybe a script to swap two different wallpapers when switching?
I have been testing for a little bit now and I've had none of the issues mentioned here so far, except that my widgets get removed when switching and the wallpaper is switched across GPe and Sense if it is a stock wallpaper.
I'll post any other issues I find when (and if!) they arise.
Keep up the good work Paul!!
I'm loving the new update... Some of the things in 4.1 really annoyed me, like the 'black bar of death' and the dock icons as the OP said. Only one issue though: I updated before I went S-OFF and now I can't. :( Oh well, I guess there's nobody to blame for that except myself. ;)
I would say the main difference between HTC's 'Music' and Google's 'Play Music' is that Play Music can play music from your purchased Play Store music, whereas HTC's cannot. I personally prefer the look of Play Music, (and I buy music on the Play Store) so I only use that. As for uninstallation, unfortunately not without root. But, you can disable them. Go to Setttings > Apps and slide over to the 'All' tab and find whichever one you want to be rid of. Tap on it, and select 'Disable'. This is almost as good as uninstalling the app, as it is completely hidden and non-functional. I have used this feature for some HTC apps which I never use (Best Deals). Hope this helps!
