A feature all poker sites should have...
 

A modification to the "pop up on action" feature available at least on PR.

"cue pop up on action"... I wanted to use the pop up on action feature on PR but then you risk trying to raise on one table, having another table pop up between your finger movement and reaction time, and acting on the wrong table. If it just cued so that once you've finished acting on the current table the next one pops up, you wouldn't have the problem, and you also wouldn't need to use a mouse or extravegant autohotkeys.

I'm imagining a cool 3 monitor set up. x tables on the left, x tables on the right, and the table which you are to act on is also displayed, full screen, in the middle.

This sure sounds like MTH. Have you tried it? It keeps a queue of tables that require your attention, so needy tables get in line, and you service them in the order they were received.

Check it out.
