- Decouple condition requests from expansion, now
pre-request when zen panel unhidden.
- Animate zen mode panel expansion.
- Improve default selection logic, ensure something
is selected as soon as we are in the expanded state.
- Tweak visual spacing.
- Map null condition to Indef properly when we start
out in zen.
- Avoid unnecessary condition teardown when the conditions
are updated but unchanged from current.
- Cap number of optional conditions to display, default=3.
