Listen to your users!!
I feel like you should listen more to your users and try to reply to the feedback. There are a lot of good ideas with no answers. At least give us some update... some planned ideas goes back more than 4 years. The majority of them seem pretty easy to implement, for example how can you not add some subfolders?
I'm waiting for a guitar tablature background for years. That would be something of the things that are really easy to implement, but it still doesn't exist.
At a minimum, spam needs to be deleted.
