** Update December 12th, 2023 **
Scrum for Trello is working again.
Thank you to https://github.com/Swandog for creating the fixes.

** Update October 15th, 2023**
Trello is rolling out changes. We are working on a fix to support this.

In the mean time there is a workaround:
If you go to https://trello.com/labs you can disable the option “Board experience enhancements”.
That will revert Trello to the old state and the extension works again while we work on a fix.

- Added a nice feature contributed by Cedric Gatay:
One thing we use often is surrounding points of done tasks with [] to prevent them for being counted by the plugin in the list total.

This contain the ability to display such tasks with a decent style (half-transparency) on cards and a differentiated total shown on lists.

Trello is the perfect online equivalent of the whiteboard with sticky notes aka the Scrum board. We love this app and started using it immediately after launch.

One element we use a lot in our projects are the storypoints. Scrum for Trello gives you the ability to make use of story points within Trello.

Setup

Scrum for Trello is a Chrome extension and you can install it via the Chrome Webstore.

How does it work?

In the card titles you can add the storypoints between parentheses. The assigned points will be picked up by Scrum for Trello and displayed in the upper right corner of the card.

For each list the total amount of story points will be calculated and shown in the title of the list.

Every second the story points will be detected and calculated. So changing a number or moving a card will be reflected almost immediately.

Updates

Great improvements made by @nicpottier and @paullofte:
* The point value is moved to be a badge on the card.
* Added support for Zero Point Cards (0), Unknown Point Cards (?), Decimal Value Cards (.5)
* In addition I added the functionality to have the list total reflect the current filtered set of cards.

More great improvements
* @bastiaanterhorst created a storypoint icon to fit in nicely with the Trello style
* bugfixes by @mgan59
* A very cool storypoint picker made by @nicpottier was integrated and adapted. Click on the title in the card view and a little menu shows you available points to quickly select. Of course you can add your own points between parentheses still.
