I have modded mine and a few others in the Bovada thread in Internet Poker thread have said they did too. I'll jump on a micro table and grab a shot.....
I set it up like my latest Merge tables were. Stars Chips, Merge Card Backs that I liked, Leather table that tedd_e_KGB posted at some point, blue buttons that give more contrast to catch my attention, Yellow spot light for contrast, dealer button from Merge Mods. The card faces are customizable, but I didn't care about changing that. As are the player boxes and pretty much anything else.
Very simple to do, no scripts or anything like MergeMods needed. Mark your files read-only and you're set. I hope the Bovada reps don't get sideways with these mods. I just couldn't focus on the tables the way they were and played very little. With these changes, I have pretty much moved all my play here.
