Looks like this is still an issue as of august 2025. I just updated my asistudio after a long time using an older version and this became immediately apparent. I depend on this to determine whether my data is worth keeping or not and which subframes to remove.
Incidentally, another bug that's been around for years now. I have an asi2600mc pro and images display in color. When I try to save them as tiff, they are saved in grayscale which is useless. I would like this feature to work, especially since I'd like to batch safe the fits as tiffs for another project.
