I have played 3/4 tables for several hours without any problems. I really like this. I don't usually play more than 4 at a time, so while the old format wasn't really a problem, this definitely makes it a little nicer.

My only suggestion, and this is minor and kind of unrelated (and has probably been discussed), is to have the "wait for BB" checkbox available as soon as you sit down. So you don't have to wait for it to be your turn to select the option.
