Hi

I thought about it a little bit, shouldn't be too
hard.

Just have to make a special constraint callback that
would handle the sliding. All the edge slide code
would have to do is fill in data structure with the
sliding vector and limits for each selected verts and
the special constraint would use that to move each
individual vert during transform (would even count as
a normal grab constrained to a single axis). That
wouldn't work with PET though, but proportional edge
sliding would probably need some special code anyway,
to only (potentially) affect verts on the same loop.

My list of todo stuff on transform is very long
though, so I'm thinking I could just explain to Johnny
what I had in mind, I'm pretty sure he can do it with
some help.
