[Bf-modeling] Mirror Editing

[Michael Williamson]

"One last thing, When importing models that are mostly symmetrical, but 
not 100% I found it annoying and there is no good way to `snap to 
mirrored`, so probably blender should have a tool that does this built-in. "


oooh, yes please! A way to bring parts of a model back to symmetry would 
be great!

Probably beyond scope of this list but a sculpt brush that restores 
symmetry would be great too!
