Suggestions I have

[tbyunomi]

-Recycling Bin
Allows users to view and undelete items that have been deleted like
-Sequences
-Playlists
-Forum Posts
The Recycle Bin would also be cleaned out every 2 months or so

-Following
Allow users to follow other users to stay updated on what they do like:
-Post a forum post
-Pin a sequence to their featured
-Create a playlist
-Add a sequence to their playlist
Idk about notifications regarding posted sequences since it would literally spam your email

-Likes
Allow OS users to like thing created by other OS users like:
-Sequences
-Playlists
-Forum Posts
