I used CSSU for about a month but changed back for one simple reason.

It's the portrait mode.

In landscape, i like to have my icons and apps arranged a certain way. When it switched to portrait mode, everything gets moved around when switched back to landscape. This basically made me lock to landscape mode, until i wanted to use something in portrait..

Constant locking and unlocking this feature is highly irritating and to be frank, i would prefer putting up with the imperfections of pr1.3 to avoid this.

If this function could be improved i'd gladly try it again as the other benefits like stability and slightly better battery performance are worthwhile.
