What is it about?
This work elaborates an SL-invariant feature which is balancedness. At the end it discusses some peculiarities of SL-invariant entanglement measures which is imported on possible measures of higher local dimension.

Why is it important?
The demand of the additional SL-invariance of entanglement measures offers, besides other important and favorable features from earlier work, a straight forward testable requirement on the states, which is the balancedness. Each state that is detected by some SL-invariant measure necessarily has this property.
Perspectives
Here we add a further goody to the invariance group SL for entanglement purposes.
