[fixed] ToolTips

is it possible to add a tooltip to a custom button, we have the ability to add button for custom tasks and it would be nice for the user to know what the button does with the tooltip, altho part of the fun with new skins is pressing the buttons to see wot it does
also no tooltips on the sliderbits with relation to the sliders, not sure if thats a bug or feature (missing?)
