Playing a Card (etc.) During Opponents Turn?

For my third wish…

I want to enable players to interrupt an opponent’s turn to do something, like play a card, discard an opponent’s card just played, draw a card.

How do I do this?

When playing live, it is of no issue, they just perform their action.

In PBEM, a player can start an “overlaying” log, when he sees it fit. Within this log, he can, first, play his card and then step through other player’s log.

OKay. Since this is a Bata Test Mod for a game to be printed, I’m going to ask people only do live plays so they don’t have to set the overlay log thingy.

I myself have yet to ever actually play a game using Vassal.
