[feature request] Efficient vertex merging

I apologize if anything like this is already available, I haven’t come across it.

But while retoplogizing I spend a lot of time merging vertices, and I really wish instead of doing each pair/segment one by one there was a way to merge similar instances all at once like I believe there is in Modo.

It’s a small detail but it really interferes with your workflow in lower poly work.

Have you tried enabling the Auto Merge option in Mesh menu ? Remove doubles merge limit ?

.What does this actually mean ? Similar in what way ?

I think he means edge merging, something I have wished they had as well. If two edges are selected and you hit merge at center, it knows to keep the edge length and direction the same, just merging them together. Would be great to be able to take two adjacent edge loops and make them one.

Adding to what Richard said, you can also select an edge ring and X -> edge collapse.
