When the pointer hovers over a tag, a tag popup appears. This is fine if you move the pointer to the tag, but it is a nuisance if you scroll the page and the tag slips under the pointer. Can you work it so that scrolling doesn't trigger the popup, but moving the pointer still does?
I rather have a consistent site that always shows these descriptions when my cursor is on the tag, than one were these descriptions sometimes don't pop-up. Adding this feature will cause a lot of unnecessary confusion.
These tag buttons are really small. If occasionally my pointer ends up on one of the tags after a scroll, I am willing to just move my mouse a bit.
