I added colored borders. Now when a table is recognized as needing your attention, a colored border is drawn around it. Colors gradually shift through black, <font color="blue">blue</font>, <font color="green">green</font>, <font color="yellow">yellow</font>, <font color="orange">orange</font>, <font color="red">red</font> as time elapses. I gave 30 seconds to Fold/Call/Raise and 10 seconds to Show/Don'tShow/Post/Don'tPost. Seems about right.
I also added an option to turn-off these borders. This will probably be a good idea if you have overlap. The borders are done in a very similar style to the blue-bar. (I have ideas about fixing them to act naturally for a user with overlap, as long as that user is using the Popup Blocker. Right now borders are constantly pushed to the top, which is good if you have no overlap.)
Play around with it; tell me what you think.
