Hi Lawrence,
For some further comments on resynching:

The mosaicking deserves some thought, and I'd appreciate
comments from you and others who are actually doing this.
How does this sound, at least for a start:
You set up the "CCD Frame" dialog to show the CCD properly
(right size, focal length, etc.), just as you normally might.
Then you tell Guide how much overlap you're looking for. It
can now reason along the lines of "the mosaic will be in steps
of delta_RA and delta_dec in each axis", with the deltas
determined from the CCD size and specified overlap.
The arrow keys, by default, cause Guide to pan half a screen
left, right, up, or down. While you're in this "mosaicking" mode,
they would instead cause you to pan by delta_RA or delta_dec.
So you'd center your target, tell Guide to slew the scope there,
take an image... then pan (say) left using the left-arrow key, image
again, pan (say) down, image, etc., etc.
This has the virtue of being pretty straightforward to implement.
All I'm doing is modifying (very slightly) what the arrow hotkeys
do in a specific situation.
Incidentally, the toolbar "pan" buttons would be similarly affected.
Any thoughts?
