Hi Rogelio,
I would like to suggest a small feature for SubframeStudio that could make visual inspection and blinking of subframes more convenient.

Would it be possible to add an option to automatically display all preview images in the same orientation, regardless of whether they were taken before or after a meridian flip?
This would make blinking through an entire imaging session much easier, since the target and star field would remain in a consistent orientation throughout the sequence.

Kind regards,
Emiel Kempen
