This is begging for a redesign. I propose the following structure, with each level of indentation with ">" indicating a submenu:
> Add to AutoDJ Queue
>> Top
>> Bottom
>> Replace
> Load to
>> Deck
>>> 1
>>> 2
>>> 3
>>> 4
>> Sampler
>>> 1
>>> 2
>>> 3
>>> 4
>> Preview Deck
---------------
> Crates
>> Crate 1
>> Crate 2 ...
> Playlists
>> Playlist 1
>> Playlist 2...
----------------
> Analyze
> Tags
>> Reload from file
>> Fetch from MusicBrainz
> Clear metadata
>> BPM and beatgrid
>> Play count
>> Cues
>> Loop
>> Waveform
>> ReplayGain
>> Cover art
>> Tags (not sure about this. Would there be a use case for it?)
>> All
> Cover art
>> Choose new cover
>> Reload from file/folder
> Change BPM
>> x 2
>> 1/2
>> 2/3
>> 3/4
>> 4/3
>> 3/2
> Hide from Mixxx library (adding the word "Mixxx" to emphasize this does not manipulate the file)
> Delete (confirmation dialog would pop up before deleting the file)
> Open in file browser
> Properties
Thoughts about fixing this for 2.1 after the feature freeze?
