I understand not being able to remove apps from an active session as it would be a silly work around.
However, it would be nice to be able to do two other things:
  1. Set up additional non conflicting schedules or edit existing not in use sessions during an active brick session.
  2. Add new apps to the block list of the active brick session.
This may really only be a problem in the first few weeks but it would make setup friction a lot smoother.
