Order shared photos before posting
Sometimes the order of the (up to) four pictures shared can have some importance, so meaning, or make it easier to understand (my use case is teardowns or repairs where first seeing the object then seeing it's insides is more logical)
Also when sharing three pictures most mastodon clients show the first image bigger than the other two, so it's nice to choose which one.
So choosing the order might be nice. Maybe also ordering them by default by creation or modification date could be a plus (not sure how they are ordered right now). This is scenario is usually when choosing the images from a gallery application and using the share to fedilab button.
