Multi-Select-in-Preferences-Metric-Column

I have several ScoreCards with a larger number of metrics.
If I want to include many of this metrics in backtests and optimization results I need to Drag&Drop each of them individually - tedious.

Please allow "multi select" aka Click first, Ctrl-click last to select (and Drag) many at once.

Also: I work through RemoteDesktop on a Server which runs WL7.
In this case Drag&Drop is rather slow and not always reliable.

Please add some Buttons " >> " and " << " which move selected items form left to right and vice versa.

Also: To speed things up:

Please allow a double click on a single item to move it to the other side.
