Usability - Make moving cards easier/less restricted

[codemonkey-uk]

It would be good to provide a way for players who make a mistake in card assignment with an method or opportunity to undo that mistake and move the card to where they really wanted it to go.

That's a tough one. Could any player do it? Only the current active player? or the previous player?

Actions are currently instantly sent to the server, we could delay that and client-side add "Do it" and "undo" buttons. It's an extra click every time, so I think people will just start doing it instinctively and it will lose it's benefit.

We could save the last few game states to the db, and provide a "revert to X" system. Fairly easy server side? Not sure what the ui would be like.

If we wanted a straight "undo" button, server side would have to remember the inputs in to the last action(s), and then we'd need "reverse" versions of each action function. Annoying IMO.

I see two paths to this:

• full undo, save state in a db after every move and restore it, perhaps using browser back button as the trigger
• we already support moving object cards between players as a free action, unlock this for all detail types
