Easier navigation accross Bone Layers

Hi, there.

I've been using Bone Layers a lot to organize my Armatures.

What would be nice is if we have a Bone Layers' "global access" (like a global, or at least a 3D Viewport's shortcut), so that we could change the Bone Layer(s) we're at any time at any moment on the 3D Viewport, not being dependent on having the Armature selected in Edit/Pose Modes.

Because there could be many Armatures (so, even a list of sets of Bone Layers) on a single project, the way I see it happen is that there would be an "Active" Bone Layers set and this is the one we're navigating priorly with that shortcut; but we could swap that Active at any time because the same proposed shortcut would first open (for exemple) a popup menu list of Bone Layer sets (especially in case of the presence of different Armatures on the same project), and by selecting the wanted one (Active), we dive directly in another popup menu of that Bone Layers set's Bone Layers (similar to what happen when we press "M" shortcut for Moving Bones around Layers. The difference is that this popup menu (probably from the 3D Viewport Editor) would be of "global access", will not be used to Move Bones, but mostly to easily navigate through the Bone Layers of a single Armature and, even more if necessary), to easily navigate between Bone Layers sets from different Armatures on the same project.

Have a nice week; Cya.
