Ubuntu session vs GNOME session 2021

Hi,

What are the actual differences between these two sessions?
Ok, I know Ubuntu’s:

  • Desktop shortcut in Files
  • panel appearance (background, straight, normal fonts)
  • appearance tab in Settings
  • (?) over amp for sound in Settings (in Tweaks for gnome-session)
  • Yaru shell theme
  • by-default activated Ubuntu extensions

What else?

Note that I’ve just modified one of my extensions to make GNOME panel looks like Ubuntu-GNOME’s panel.

Hopefully Yaru team won’t ask copyright. :wink:
