[galaxy-dev] Balloon tooltips

Hi, I was wondering if there's an easy way to disable the pop-up balloon tooltips (on the save, rerun, view, delete icons) ? The new beautiful icons (or the old text-label) are informative enough - and the constantly appearing/disappearing black tooltip balloons (when you move the mouse over datasets) is a bit annoying. Alternatively, is it possible to add a short delay before showing the tooltip (like in all regular GUI client-side applications) ? Thanks, -gordon
