It might already be possible to do this in CV 5, but I haven't figured out how to do it:

Create a button at the bottom of the screen (like the "Deal" and the "Rebet" buttons) to 1) force a Shuffle, and 2) Pause the Game.

Having a "Shuffle" button at the bottom of the screen would make Wonging in or out much quicker. Having a "Pause" button would simply make it easier to pause the game if you want to ponder your next bet between hands without CV beginning to deal before you have placed your correct bet.

Going through the "File" menu at the top is O.K. but the buttons would be faster and easier.
