I was also disappointed that they dropped Unity.

I stayed on a workable Unity install on 2020.05 LTS for as long as possible, then switched to 2024.05 LTS, at which point Unity, for some reason, no longer functioned (even though I was using the Ubuntu Unity flavor). Tried Gnome for a while but what ultimately lost me was the notifications. To close out a notification without switching focus I had to, very carefully, click right on the X in the upper right corner. Otherwise it would activate the notification and switch focus.

I've got a workable setup with XFCE4, the whisker menu bound to the super key, a few panel plugins to make a maximized app have the same behavior as they did in Unity, and the Plank docking program (along with a brief shell script bound to the dock that kills and relaunches Plank when it starts moving out of place). The notifications work the same as they did on Unity - clicking on them dismisses them unless you click on the "activate" button to switch focus.
