Ability to import commands from legacy menu

[thomassth]

I remember some "system tweak" apps can access what other program put in to the right click menu.

Ideally, we can pick what we want to use, and copy said logic to the new right click menu. Some adjustments may be needed to be done manually but it would be easier to do everything from scratch.

It is indeed a good idea, but it may take a while...
