I finally took the plunge & went ahead to install the CSSU. It's currently at v15.
The install process was painfully slow. I'm not sure why, but downloading supposedly 28MB worth of files took well over 6 hours. I had leave it overnight. Fortunately, when it was done in the morning the upgrade went without a hitch.
The resulting desktop was by all accounts completely identical to the one before. I had to do some digging to make sure everything was working as it should. Only a few things were visible:
- an Orientation Lock button appeared in the status menu.
- the application menu rotates to portrait.
- the status menu rotates to portrait.
I immediately installed the CSSU Feature Configuration Editor & switched on the new 2 column task manager.
Have not run into any issues yet, but it's too early to tell, a couple more days & we'll see. So far, so good.
