1. Smart playlist import from Traktor is totally missing. I think this is essential to be able to say you can import a DJs Traktor Collection. MIXO import is not reflective of the Traktor collection.

2. Implementation of Smart Playlists within MIXO itself is very limited.

a) It's lacking in fields available.

b) The criteria is limited to a specific tag. You can not do for example, starts with. The use of 'tag' for a criteria is very limited and confusing. I'd recommend just freeform text in conjunction with better condition definition.

c) They aren't editable. Not a huge deal, but makes sense to be able to edit them.
