Suggestion for = "Pixelscape Dark" pack

[ghost]

The current highlight for selected spells is very subtle, only slightly affecting the corners. It can be difficult to tell if I've clicked on a spell, especially if I click quickly; this is highlighted in PKing, for example. Making the corners more visible would make things much clearer.

I've provided a picture of the current highlighting; the spell highlighted is the ice barrage, which is located at the bottom left corner.
