Is it possible to make the rep button bigger, like the thanks button is, so more people would notice and use it? Perhaps even the same button could be used to access both systems, and it would pop up a dialogue asking if you want to give thanks, positive rep, or negative rep?
It is bigger now, bigger than the Thanks button. I don't think that they can be placed side by side, and not sure if there's delivered functionality to merge the two together with one button. Hacks make upgrades more difficult to implement.
