I installed the CSSU since it first public release and have no preblem with it so far, good work
I have two suggestions:
-A gconf key to deactivate the menu for changing position of applications that PR1.2 introduced, I use ApMeFo for reorganizing applications so it is totally useless to me plus something it launch itself for no reason, which make the phone irresponsible for 3 seconds.
-A gconf key to select the root of file selector.
