This seems like something I could look into. Many of the recent improvements (additions) to that widget are things that I added. On the surface this seems to be not that difficult. Please add a feature request in bugzilla for this.
For the second issue, this is easily handled in script. There is a message for ‘hiliteChanged’ that you can use to clear the highlight. You just need to trap for empty so you don’t create a loop. We use this approach in SivaSiva where this widget is used a couple places as a menu. It is useful because you can have the highlight show briefly to indicate the touch/click happened.
