A little UI tweak which would be nice: if you click on an opportunity card and then decide you don’t want to use any of the branches, there should be a button to discard the card right there and then, rather than having to click "perhaps not" and then "discard".
If something works perfectly then there is no need to fix it.
Eh, I kinda worry this would lead to more misclicks and accidentally discarding something you wanted to use.
