Allow cards to be in draft mode : Think-Write-Tell-Place
When conducting a meeting that is geographically distributed, people come up with ideas while others are talking. So in the "Think-Write-Tell-Place" methodology, it would be great to be able to "write" while someone else is talking, but not have it show up for other people until it's your turn to talk. Then, taking it out of draft mode will allow it to show up on the board when you get the opportunity to talk about it.
