Add support for app ratings and comments
I think it would be very necessary to add the opportunity to rate and comment the apps in f-droid. If one would recognize that a app was a manipulated fork of an other app with malicious code, he can't tell this the others. And many other user would download this app and won't recognize it.
And if I was a developer, I like to get feedback.
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
