Button spacing feature request

Fairly new user here. I can't find this subject covered anywhere so I'm posting a feature request.
I use horizontal and vertical toolbars. It would be nice if the button spacing settings could be targeted to individual toolbars instead of a app wide setting.
This would make my vertical toolbars sleeker without crowding the buttons on the horizontal toolbars.
If there is already a way to do this via some command line I would appreciate someone pointing it out to me.

Thanks

There's no way to do this currently, but we'll put this idea on the list for a future version.
