[Feature Request] "Set Vertex Flow"–like tool for smoother mesh & "Loop Edge" selection tool

I’d like to request a feature similar to “Relax Vertex” or “Set Flow” in Blender3D, adapted for Live2D Cubism. I’m not sure whether this fits Cubism’s current design direction, so I’d like to hear your thoughts. It’s not an urgent feature, but I believe it could significantly speed up the workflow.

In Blender3D, these tools help even out vertex spacing and improve edge/flow consistency without drastically changing the overall shape. This is extremely useful for achieving clean and natural edge flow.

In Live2D, managing vertices one by one to achieve good flow can be time-consuming. Because of that, I feel this feature would work best if it were added together with a loop edge selection tool. Selecting vertices individually just to adjust vertex flow is inefficient.

Requests:
- Loop Edge selection tool
- “Set Vertex Flow” / vertex relax feature to automatically improve vertex spacing and flow
(optionally with a strength or iteration slider)

I’ve attached an image example for reference. Thank you for considering this request!
