Copy to clipboard button

[brainysmurf]

I'm trying to not have too many buttons, but there's a good argument for having a copy to clipboard button. Copying the formula to the clipboard needs to be smooth and easy. Currently it takes too much fiddling. (Clikc on Edit, select all, then copy)

Not sure where to put it though. Sidebars have so little room and I'd prefer that the formulas have enough space.
