Definitely good and useful ideas!

I had a couple of similar requests in the past. (Beginner / Advanced views)
Now, reading your post, I think the best way and future proof way to tackle this would be a fully customizable quick access menu button that would load essential menus/functions. Meaning, PG can have several templates (Beginner-Intermediate-Advanced) or custom where users can select group things to suit their workflow. That way nothing is set in stone and can be changed as program develops with ease.

I am not sure if you are aware, there is a "custom" tabbed quick access item, which you can make use of.
See attached.
I wish there would be a way to add more specific/direct functions... Maybe that is the way to go...
perhaps renaming "custom" to something else, add more functions / shortcuts and have it as default tab?
