I think there's other ways to flatten the images that are easier. However, this is fairly quick to produce many crops quickly just by rotating the sphere and saving the new project file. All three of these images are made in a few minutes with the crop technique. It might be useful for surveillance, construction, or even social media if you reduce the width.
Maybe something like this below with the caption, "stuck on land helping Dad take pictures #wannasurf"
this is the original file for all the images in the two posts.
