Points for Trello

Trello Points activate a "point" system in cards of Trello boards.

Those points are cumulated and displayed in the list titles.
That allow cards to have a "weight", it is up to you to decide the meaning of that "weight" : days, $, hours... as you want.

Trello Points just make the sum for you, and add some other cool stuff (percentage, ratio filtered/visible)

Do not forget to customize the way Trello Points behave, just display the "Options" panel (right click on Trello Points icon on Google Chrom toolbar").
