UV Overhaul!! Proposal 3 - New UVs Tools/Operations

Hi Everyone! Continuing from Proposal 2

As you may know one of the most lacking aspects in blender and slowest by far is editing UVs. It has always been a pain staking process without the use of external addons (free or which charge for basic functionality) that should already be in the software upon startup. Let me remind you that these proposals are only ideas to inspire anybody who wishes to provide the blender community with new features. Please note also that I am aware of the Magic UV addon in Blender 2.8 and its a really great start to adding free basic functionality in the UV workspace. However new useful operations could be added to make UV life much easier so lets get started with a single idea.

One thing i feel could be added is new UV operation that would allow island stacking to be easier in certain scenarios such as a "Stack Similar" operation. Every single UV island with similar amounts of verts, shape and size will be stacked automatically unless pinned. It would make the game art pipeline a bit faster in the texturing phase i feel, especially when editing meshes with very similar features that can share the same texture space.

This is only one idea and i encourage people to come up with their own and share them to inspire others! Brainstorming is the best way to come up with useful ideas regardless if they are practical or not since they will lay the foundation for better solutions/features to arise.
