This PR is a rollup of several enhancements and updates based on user feedback. Pending changes from Abby's feedback which Ehud is reviewing as I open this.

Yea, you prolly haven't gotten to that part of the code yet (it is the commit I made on our call) but it does that for the end user too when they hit that send button.
