It would be beneficial to display the total number of already orthorectified images during the "Build Orthomosaic" process. For large-scale projects, it can be challenging to estimate the remaining time, particularly as the estimated time and overall progress bar tend to fluctuate significantly throughout the process.
Suggestion:
After processing each group of 20 images, display the number of orthorectified images alongside the total number of activated images in a line within the "Details" panel of the progress window. For example:

240828_125500191_Camera_2: 18304x19960 -> 17907x19763
