Renaming the Shapekey set in the shapekey panel

When you make shapekeys and you want to use them for drivers you need to select the shape key group. But you can't rename that group except hidden in the NLA editor. The group name should be editable where you make your shape keys, so that you don't have to click blindly on all the shape key sets that you have. (I work with like 20 sets and it's hard to find the right one. )
