Hey Andrew, could you add the function "mark as adult" for photos and video? The most famous Dolphin competitors do not have this feature yet. It would be useful for those who want to build a community.
Also it would be interesting to have the ability to send files to another user through the mailbox. Maybe sending the file directly as it happens on messenger or by attaching one or more files (and link) from your photos/videos/files folder.
One last thing: you can make everything translatable see more in dolphin? Much of the administration is not translatable (you can only do that by editing the database), and the same goes for the titles of many icons on the site (such as "Add", "Remove", etc.). It would be nice to translate all through the language file.
Ps: You are doing a great job!
