To eliminate holes in my meshes it would be nice to be able to combine edges or verticies.
In my attempt to make a pyramid on top of my cube I subdivided the 2 top triangles, deleted 2 of the resultant triangles but then was left with 2 verticies and 2 pairs of edges that I wanted to combine.

I'm not sure how important it is to have meshes closed but I like them neat.

Combine edges, fill holes, merge vertices and split edges will be rolled out with the next update in about a month or so, but I am working on a new application for the collection that I'm sure will be received well 

Happiness! Except for the torture of having to wait...
Still, I'd rather wait longer for better features than have you rush out something broken.
