Fixes for
1. "Indicator Applet Complete" has quit unexpectedly popup
2. The unplanned arrangement of desktop icons
3. Random closing of the brisk menu
I do think UM is a great distro. 
Fix login for multiple users. I share a UM desktop computer at my home. There is a bug in that you cannot always click on your password space to sign in after someone else has logged out. Sometimes you have to click on another user first to get the focus, then you can click in your space to put the password in. Sure, I can do it, but it's hard to explain to senior citizens.... (I use 18.04. Apologies if fixed already)
