Topo Tool
Raxx:
Hey Steve, almost there!
Collapsing (LMB+Shift) isn't the same as dissolving. I was going to make some sample images but remembered nemyax did the same thing a while ago in this post: http://www.anim8or.com/smf/index.php/topic,4619.msg37601.html#msg37601 Dissolving is extremely useful in tandem with the topo tool, whereas collapsing is not. Basically if heals the mesh without affecting the surrounding components drastically. I'll see if I can provide a more in-depth video later.
If I may suggest, to change RMB+Shift to just RMB for moving points/edges. This feature will be used as often as the cutting action itself, so the shift just adds more burden to the user. Also, currently it's easy to accidentally dissolve/collapse components instead of move them, and vice versa.
It works with arc-rotate just peachy :)
Raxx:
Here's how dissolve works in XSI. It's actually the "delete" tool in that program. It would be nice if this was also the main "delete" function of Anim8or when in point edit mode. To do the original delete function, Ctrl+X can be used.
This way, for the topo tool, holding shift can become the modifier to toggle the select tool instead, with LMB, MMB, and RMB behaving as single/subtract/add select functions. RMB remains the move edge/point tool, and LMB the cutting tool. Deleting dissolves the selected components.
Just an idea for making the topo tool more efficient.

It doesn't show it in this video, but deleting faces removes the entire face making a hole in the manifold (like it does currently in Anim8or). However, deleting a group of faces removes the selected faces, as well as any p/e not connected to unselected faces.
Steve:
OK I'll give these topo tool suggestions a whirl. I'm still not sure about what to do if it creates an isolated island, or a good way to know if that's going to happen. I guess there's always undo :)
I need to study your XSI video more though.

Now that you have a collapse function, could you make it available as an Edit menu command applicable to all current contiguous edge selections? It would be a more convenient way to collapse, especially because you often collapse stuff wholesale (for example, edge rings).
Steve:
nemyax: I don't really have a general collapse tool, just the special cases of a single point or edge. But That was easy to add on top of the basic utilities inside Anim8or. But I'll see if I can add one - it does seem useful.
