How is moving between an editor and terminal splits any less effort than moving between separate editor and terminal apps? They both require either one keyboard shortcut or one click to go between? What’s the difference?
I use VSCode very happily after using Gedit for many years, and it's just the layout I'm attached to, I suppose.
The important thing is to set the desktops to be static (disable the “smart” rearranging) and set the windows to always open in the same desktop.
This makes my experience on a 16” screen so great that I have a hard time adjusting to using two monitors.
