Create 2 toolbars for different size monitors but use same buttons that update to both toolbars

You've helped me create a button that will toggle between 2 different horizontally Sized toolbars -
though each toolbar has the exact same buttons, just the spacer sizing changes -
but updating-changing-adding buttons requires that to be done 2x - obviously 1x for each toolbar.

1 button Toggle between 2 Toolbars to show - hide alternate the toolbars

The only different button is the Toggle button itself - different for each monitor:

Toolbar "!!...BIG-SCREEN" TOGGLE
Toolbar "!a.....dmh-main-toolbar-Office" CLOSE

Toolbar "!a.....dmh-main-toolbar-Office" TOGGLE
Toolbar "!!...BIG-SCREEN" CLOSE

Is there a way I can create a 'common button set' for all the other toolbar buttons -
that will apply to and be used by both toolbars -
such that any changes to the 1 button set will apply to both toolbars? Thanks

Are you doing this because you switch back and forth between a touch screen and a mouse? Because Opus has a UI spacing feature which lets you do this automatically (or manually, but it means you don't need to make copies of your toolbars just to change the spacing).

No - just between 17" laptop and 32" monitor

But do you use them at the same time? Or are you switching between them?

Not at the same time - I either hold-drag dOpus back/forth depending on the tasks,
or - believe it or not - Actual Window Manager's "Move" title bar button finally plays nice with dOpus!

If there's a better way to do what I'm doing, I'm happy to learn!

Then UI spacing would probably do what you need. Check it out under Settings / Preferences / User Interface / Spacing.

You can switch spacing modes via a command (so on a button or hotkey) as well, e.g.
set spacingscheme=!mouse - mouse spacing scheme.
set spacingscheme=!touch - touch spacing scheme.

I'll try that now - btw - I did try searching the Manual, but -

Docs.dopus.com - Is Docs Down Right Now? tells me it's down for everyone

Thanks - it needed a reboot and a good talking to. Back up now.
