Are there more refined methods of zooming?

[Jason Hinze]

The only zoom controls I've found in OmniGraffle are the
"actual size", "zoom in" and "zoom out" menu items and
and the zoom picker, with 25%, 50%, 75%, 100%, 150%,
200%, 400%, and 800% settings.

These controls are far too coarse -- the "zoom in" and
"zoom out" seem to operate only by a factor of 2x, and
available choices in the picker are too far apart.  What
I'd really to be able to do is Adobe-style zooming:

   1) Fit to window (command-0 in Adobe apps)
       This is the biggie.  Can't live without it.

   2) Something like the command-space-drag function
       in Adobe apps.  This zooms the dragged-out area
       to fill the current working window. This is also a biggie,
       especially for working on very large drawings.

   3) Smaller steps for the "zoom in" and "zoom out"
       commands.  If we have #2, this is a nice-to-have,
       if not, it's a must-have.

Are there any features like this in the current version of
OmniGraffle that I'm just to boneheaded to discover?
If so, please enlighten me.  If not, do y'all think these
features would be useful as well?

Thanks,
Jason Hinze
