Multiple elements at the same line

Right now each new element (arrow or note) is drawn at a new ‘line’.

It might be neat to also allow multiple elements on one line - though it’ll probably be up to the user to make sure they don’t cause overlap.

This could be represented using indentation:

A->B: Broadcast trigger
B->A: Broadcast message
  B->C: Broadcast message
  Note right of C: Yay!
B->A: Delivery ack

  A                     B                     C
  |                     |                     |
  |  Broadcast trigger  |                     |
  | ------------------> |                     |
  |                     |                     |
  |  Broadcast message  |  Broadcast message  |
  | <------------------ | ------------------> | Yay!
  |                     |                     |
  |     Delivery ack    |                     |
  | <------------------ |                     |
  |                     |                     |

+1 I was looking for a way to have concurrent notes. At least those are not ambigous.

Maybe the start of a line can have a small dot.
