Single popover for all commands?

My favorite feature of Dorico remains the popovers. I find there to be a little bit of overhead remembering which keyboard commands trigger which popovers and which popovers accept which input.

Is there a universal popover that accepts all, or a wider variety, of input? I see little conflict between the things you can type into the different popovers so it seems technically possible, but maybe there is a reason they are separate.


See here, for instance.

It just occurred to me - what if typing a question mark into a popover showed a list of all popovers?

You can see most, if not all, of the popovers listed in the Write menu.
