Remove duplicates from Playlist

Several Playlist Improvements:

1. Remove duplicates from Playlist
2. Filters on the playlists.. To say with 1 click you can filter anything in range 100BPM +- 8%
3. Colors of the BPM - slow (50bpm) is infrared to fast - ultraviolet (160)
4. Another row on the favorites - Slots are not enough.
5. Lock playlist - cannot be removed, cleared, no files can be changed or removed from it, and can't be moved. Sometimes we drag things by mistake..

Other improvements:

Something that is not related to playlists, but.. there is still no REV button even in 2.6.1,
This is when track goes to play backwards. And there must be a setting - how fast it goes to play backwards.. - does it stop slowly and start slowly to full speed, or it is immediate.
This should be a button, not effect.

 

1. Already there, righ/ctrl Click Remove Duplicates
2. Just hit the BPM field and choose the closest tracks ? Maybe I misunderstand
3. Why not. Dunno if would use it but it would look nice
4. +1 although maybe not a row just more slots
5. Already there. Consolidate Playlist

 

Thanks
