Using Ubuntu 20.04 and Gnome Session Flashback, I got accustomed to the title bar icons being on the left. I've found that I prefer the 'close' button to be closest and within reach for quick access, then the 'minimize' button where the 'maximize' button is furthest away; being that by double clicking title bar toggles maximize anyways.
I've tried
gsettings set org.gnome.desktop.wm.preferences button-layout 'appmenu:maximize,minimize,close'
Which results in the orientation of the title bar buttons switched back over to the right. "Gnome Tweak Tool" still shows it on the left.
Any help, much appreciated.
