It would be nice to be able to choose where in the scene your post should be put. For example:

Jane posts: Jane pulls Sarah aside for a private conversation.

Bob posts: Bob and Randy are busy working on making the truck work.

Then when Sarah comes in to post instead of her post just going to the bottom she could select it to come AFTER Jane's post and BEFORE Bob's instead. This way Sarah and Jane could have a private conversation without being mixed in with all the other action going on. This could potentially be a way to have 'two scenes going at the same time.'

Of course this function would probably require a "NEW" tag to show that a post was just posted within the scene and not at the end so those posts aren't missed.

Just an idea.
