Instead of right-clicking on the folders, clicking groups, and clicking the desired group, it would be nice if the groups were listed on the title bar. Or maybe a Groups dropdown.
You can put them on a toolbar, if that helps.
I don't see an option under Folder Tabs or Toolbar. How is your suggestion accomplished?
Settings > Customize Toolbars, to start editing your toolbars.
And you can find the command to list Folder Tab Groups in the default Folder > Folder Tabs > Tab Groups menu. That can be copied to a top-level toolbar if you want the list to appear there.
I'm old and slow and stupid.
When I right-click I get Preferences and Customize. I don't see Settings anywhere.
Also, I can't copy anything from here.
Customize is what you want. It was renamed some time ago but your toolbars may date back to an older version.
