Let me respond to your new suggestion!
1. I will give this some thought.
2. Also, this needs some thought.
3. This will come in Beta 4.
4. This will involve quite a bit of work, but I'll add it to my wishlist.
5. Sorry, this would just be an epic amount of effort, this isn't planned.
6. I'll play around with this and see what I can do, but I'm not hopeful that the editor control supports this.
As for calling another Macro, this function made it into Beta 4 and I'd love your feedback:

I would love any feedback you have, as much of Beta 4 is shaped around your excellent ideas. Thanks!
