Disable Tabs Altogether

[Jopp]

Ops, i forgot about, i already implemented this in my own theme Dune

But you are quicker if you add the css rule from this post:

Tab Stacks/Sliding Mode: Add option to show only one tab a time with two collapsed stacks on the sides (full width tab)

Here its a QUICKFIX for those who want to have full width sliding panes. Add this custom css snippet body { --tab-stacked-pane-width: 100%; }
