It would be very nice to have the ability to edit the photos and have the option to crop and rotate them.
We already have an orientation field in our index that is used to fix the rotation. However it would be best to fix orientation directly in the image (exif header) so that all apps show it correctly and you don't have to manually fix it every time.
Actual photo editing is out of scope for now, there are other projects (incl Photoshop) that provide this already in great quality. Note that many users don't want us to modify their originals at all, not even rename them.
Would it be easy to expose this orientation field in the edit dialog?
Might be added to the files tab in addition to "Portrait: Yes/No"... note that the orientation might be different for each file in a stack (files that belong together):

i would love this too, also move from album to album or delete a pic
upvoting simple rotation would be great. Ideally from the main photo view, but in the edit window would make sense as well.
