This is a small quality of life thing that would speed calibration.  During Calibration, if I get the "Select the Correct MasterDark" popup, please pre-select the MasterDark with matching exposure length in the drop-down list if it exists.

Also, please pre-select the checkbox "apply to all light frames with same ISO/Gain ..." 

I always have to do these two steps and then click OK (and usually OK on the next dialog box that pops up).  

If you made these two pre-selections, I could just hit enter once on each dialog and get on with calibration.
