Improve overlay visuals #20
Description
Currently the overlay is drawn and remains over the widget/item the entire time the user is on that step. This is an awkward experience in some cases where the user might click a button that then disappears because the UI changes, but the overlay is still drawn over the pre-existing spot.
There are several possible solutions to this problem. One from @micronAMZN would be to make it so the overlay only stays for a couple of seconds, and has some kind of pulsing animation. This would do a good job of drawing the user's attention to the action they need to take, and then once it disappears we wouldn't be have to worry about it being drawn incorrectly.
