Wish: Chamfer edges and Chain-selection of seams enhancement for mesh converting purposes and easier/faster mesh unwrapping

Hello, it would be awesome if you’ll want to consider to add in the future those two behaviors:

Chamfer Edge: An option to enable / disable to prefer the creation of triangles or quadrangles between intersections.

Unwrapping of meshes: Chain selection.
Each time you use chain selection on a mesh with triangles, you will end up to manually select between 2 edges (or more) regardless on how you fine-tune angle tolerance. But in my workflow I found that almost every time you will want to select purple edges marked by edge tool (unwelded edges I guess?) over non purple adjacent edges. So… it would be extremely useful an option to chain select directly only those marked edges. By doing so, unwrapping would be much faster.
