yeah, i've had that, where the notification bar will stay down after clicking an app. i just roll it back up and the app i selected is no open in the background, so its all good.
and as far as the notification light goes, i wish there was a way to also tap into that orange/red LED as a notification light. I downloaded an app that can control the blinking light and for various things, and if the phone supports it, multiple colors (dunno what phones have a multicolor LED there...) but seems it can only tap into the green LED. Which sucks, cause i'd love to have missed called and voice mails linked to the red light while everything else linked to the green light. maybe once its rooted and custom roms come out that'll be an option.
