This concept to me has been non existent but now that i’m aware of it I think it would be extremely useful.
There has been a few similar mentions like here on right click select bu mostly it’s not been a thing.
What brought this on is mostly Marvelous Designer users, who need their UV’s to be consistent but also need to retopologize the often messy models MD generates. But now with MD9 they added the ability to topologize the model based on it’s UV or “Pattern”. The tools while barebones change everything.
Apparently this has long been a maya feature shown here.
Blender could absolutely use some tools to help work with this type of scenario. I’m mostly posting to bring some awareness to this idea after discussing this with some other artists who needed a solution for this.
