I normally run Bartender4 with visitibility of [nocombat]fade with transparency of 10%. I would like the ability to optionally highlight/hide my bar(s) with a modifier key.

Request
Add functionality to allow [mod:ctrl]show|hide|fade for all meta keys

You should be able to put that in as a custom visibility condition, no?
The custom input was specifically designed so that I don't have to carry a button for every single macro conditional.
