#92 Clustered Labels

[Anonymous]

With 50 or more labels, the interface becomes cluttered.
It would be great to be able to cluster labels.
For example create a label cluster named "electronica" and let it contain the labels:
"trip hop","minimal","big beat","ambient"....
A label could be part of more than one cluster (container)
The application should treat label clusters the same as labels.
When setting a filter on a label cluster the result should contain all labels in that cluster.
