ui: selectively display promotion buttons
krancour opened this issue · comments
Follow-up to #1842
We used to allow promotion to "control flow" Stages, but such promotions always succeeded instantly without actually doing anything.
#1842 removes the ability to create such promotions.
We need a complementary UI change to:
- Not display the target button on the left of a control flow Stage.
- Not display the truck button on the right of a control flow Stage if all its downstreams are control flow stages.
Duplicating this to #1867
