Please add a new level to Plans, an Master Plan. When using narrow band filters, it is not possible take all picture on one night, you have to continue later, possible several weeks later due to a weather conditions. Master Plan should contain all pictures what ever they are, narrowband ones OIII etc. and darks, flats etc.. When done, they should be able be marked as "ready" and continue plan from undone ones, without resetting whole plan. Maybe this can be achieved just giving us a possibility in current Plan to mark its parts done/undone, just as reminders where to continue next time. Maybe Plan should also contain information of camera field rotation so that before continuing the plan in coming nights, it requires correct rotation compared to previous pictures in plan. Pictures without same correct rotation are more or less useless in stacking.
