Is it possible for the bias, dark, and flats locations be remembered from the last used location for each? What happens now is the last folder location opened is where the next dialog looks when needing a file. For instance, in the Image Calibration tool, you need to open many folder locations to choose the light frames, bias frames, darks, and flats. In my case, I keep my calibration frames in separate folders as I use static libraries for my bias, darks, and flats. If you start at the beginning and open the lights folder to choose the images to calibrate, when you move down to the bias frame needed (if any) the chooser will open the lights folder just used so you browse to the bias folder. Then you need to browse to the dark folder for the appropriate master dark which the choose opens the bias folder you just accessed and so on. It would be very nice to have the option of having static locations for the bias, darks, and flats folders. This is a feature used in another software package I use to use and really saves time. I use folders marked STL-Bias. STL-Darks, and STL-Flats to keep my library of calibration frames separate from the lights as I use a seasonal library and update the frames as needed. As the weather is getting cooler at night now I'll do a series of new darks at -20, -25, -30, and -35. I realize that I can use a master bias and scale my darks but I have never been happy with the attempts I done in the past and have plenty of nights to generate these masters.
