Vertex Group Management

Vertex Group is powerful, is useful and it has many uses, however, because it has so many uses, I think it will make it very messy,

You use it in Particle, Simulation, modifier, armature and many more, and if you are using armature I can imagine your vertex group would be very overwhelming

so what if we use some sort of Grouping System, perhaps like folder in layers, or using a treeview of some sort to organize the information, perhaps a tag and filter would be great as well.

If grouping system is not simple in the listview, then perhaps a tag and filter system will work well

I could imagine the same system can be apply to shape key as well, for organization purpose
