Having a Geoserver instance with >100 styles defined, and not being a sld-king. I often have to fix an sld, check the result and (re)fix the sld again.
From my (user) standpoint it would be much easier if after the 'save' of the edit we would go back to edited style again, instead of to the long list where I have to use search again to find the style and then click it again to (re)edit.
Not sure IF it is an easy fix (not familiar with wicket workflow), but this is one of my longstanding wishes
Making it an option would also be cool off course (given that others probably will want to go back to the list).
Same for layer list by the way....
