Trello bookmarklet to (re-)calculate sums of "points" from cards.
"Points" can be anything numeric (no units). Just prefix each card you want to count with the points in parentheses. E.g.
(3) Investigate options.
It's okay for cards to not have points. They just won't be included in the sums.
The sum of points for each list will get added to the list title in the same way as cards. E.g.
(17) To Do. Any existing sum will get updated.
The list's actual title (e.g. if you refresh) will not be updated; only the "display" title at that moment will be.
Example: I'm planning my wedding's seating arrangement, so I have a list for each table and a card for each party. I prefix each card with the size of the party, and hit this bookmarklet to calculate each table's total.
