This shows: column moves; changes because of dragging a card to a different header; and changes which will be caused by triggers.
Not implemented here:
- Actions are currently shown even if they have no effect. For example, if you drag a "Normal" task to a different column, it says "Change priority to Normal.". I plan to hide actions which have no effect, but figuring this out is a little bit tricky.
- I'd like to make "trigger effects" vs "non-trigger effects" a little more clear in the future, probably.
