My all time favorite gnome (scoff if you like, but gnome is my choice – best suits my work style) extension is workspaces-to-dock. It’s far better than anything gnome offers. The original maintainer put down his load due to personal time constraints after gnome shell 3.36. RensAlthuis picked the project up long enough to adapt it to gnome shell 3.38, at which point it seems to have been totally abandoned.
It was with great pleasure that I found that Zorin 16 was using gnome 3.38 and that workspacess-to-dock works perfectly in this environment. This is why my distro choices for real work are now Ubuntu 20.04 LTS, Zorin 16, and Debian 11. Zorin 17 will probably see workspaces-to-dock gone once more, but Debian 11 should be around for nearly five years still. As I will turn 86 in Feb, that will probably see me out.
Why no one has picked up the project I really don’t understand. I don’t possess the skills to tackle the job, and haven’t the time left to acquire them, but I certainly wish that someone would shoulder the revival.
