ALSO display "Supportable skill" @ Gemcutting Window (like it does in the inventory)

I know there are tabs for the active skills on the left side, however, I'd very much appreciate to see the Supportable Skills window there too (as it shows when I hover over a gem in the inventory) to check if said gem also fits another skill. The feature already exists (in the inventory tab), I see no reason why it shouldn't also display in the gemcutting window.
