Confirm action with timer?

[Fearinn]

It has a very good use, for actions where you have no choice.
Like not having enough money to buy anything.
Rather than slowing the game, figure it out, post a message in the action bar.
Have the ‘Done’ button count down and click.

I agree, but only if you're talking about actions that involve private info (e.g. Sea Salt & Paper). If everyone knows the active player can't perform any action, skipping that state altogether is probably much preferable.
