The ability to load and slew is great, I've been using it heavily for the past month to manually run capture jobs for long-running projects.

Unfortunately I don't see a way to load and solve an image to schedule a job. Basically I'd like to load up a couple of FITS files and say "after astronomical twighlight, keep accumulating light for on top of this photo for a while.  Once you've completed that (or when you lose guiding), start accumulating light for this other photo until dawn." I know I can define a job with coordinates, but letting the plate solver do it for me would be nice.
 

You can create a new scheduler job for each FITS-File. For each job you can define a FITS-File (in the FITS File textbox) which will be resolved at startup. Now each job ist perfectly aligend to your FITS.
I hope that answers your question.
