Will be good to have feature on image files for attach file comment to specific place on image, like in many other cloud storage solutions (eg Dropbox) with numbers 1, 2, 3, etc.
I don’t know what you mean exactly, but I think this i possible with the App OwnPhotoCloud which supports seafile.
I talk about comments attached to image area, here is screenshot from Dropbox web interface: https://i.imgur.com/XgBT9OS.png
I think that’s cool, but really not nessecary. They shouold get other things to work.
