I've made a small cosmetical change to QS. The changes are available on GitHub. The only files that changed are /asp/includes/javascript.asp (needed) and some more in the /asp folder (but you don't really need those).
I have used some more padding, a less agressive border-color and rounded borders for text-boxes, selectboxes and textareas. This affects both the backsite and some modules in the front (forms, polls, myprofile, guestbooks, etc). It somehow makes QS look a little less nineteeny I think. Hope you like!
