a GNOME shell extension
I don't have the time or drive to dive deep enough into GNOME to competently maintain this extension. Besides, I don't even use it myself anymore. If you're interested in taking over this project, my contact info is on my website: https://www.denizaksimsek.com/
The code of this extension is mostly extracted from Vertical Overview by Rens Althuis, retrieved 2021-12-21.
While I am used to the horizontally arranged workspaces of GNOME 40+, I quite liked the static wallpaper feature in Vertical Overview. I often use maximized windows on every workspace, so I don't have many chances to see my wallpaper.
Having been unable to find an extension that does that without touching the rest of the overview, I extracted the parts I wanted from Vertical Overview and touched up the animations a bit to create this extension.
