Hi Will, that's looking good!

#1, filename incrementing - this is possible if you set up a keyboard shortcut. Go to Options / Shortcut keys, and add a new entry. Put in "Alt+S" (or whatever you like) for the Key part, and "IncrementalSave" (without quotes) for the Command part. With that in place, you can then push Alt+S to do an incremental save, your file will be saved as filename01.3dm, then filename02.3dm, etc...

#2 - I'll add some way to control this for the next beta.

#3 - I probably won't be able to add that exactly for V1, but there are a couple different things you can do to help. First, if you select the object you want to focus on (it can be a sub-object like an edge or a face), then push "Reset" on the view controls panel, it will zoom to show that object and also set the rotation pivot point to the center of that object. So any rotations after that will pivot around that selected object. (Right click on reset to do it in all viewports).

If you want to focus in on a particular point, say the corner of a cube, then you can use the Area zoom button in that same view controls panel. Click that and the snap the zoom center point on to where you want to pivot around, and drag a zoom box. When you finish, your view will be centered on that point, and it will also be set as your new rotation pivot as well.

It's going to be a little difficult for me to make any changes to allow pivoting around some point other than the center of the screen, I don't think I will be able to do that for V1.
