I am a new user of dopfiles and I already have a few suggestions for new features.
File versioning :
1/ It would be great to have the option on admin side, an option that you can turn on if needed.
2/ Versioning on admin side, for each file you could see a list of all versions available and have the possibility to delete and set a version of a file as the version to display.
Upload frontend :
1/ That would be excellent to include the possibility for a user with specific rights to upload a new file and/or update an existing file via a clear and simple formular.
My last suggestion was about being able to set up a theme on a specific category but this has been already asked.
Thanks for taking these ideas in consideration for future developpments.
