Trello Groups от Hillary M

Trello limits its view to an infinitely horizontally scrolling web page that limits how much information is displayed on your screen. This extension allows you to create groups to organize your lists and scroll vertically as well as horizontally.

* To create a new group, add the | character to the header of any list. This will create a new group below it.
* Any text after the "|" character will be the group name
* Long titles will cause strange formatting of the lists, but otherwise will not break anything. I recommend limiting them to approximately 20 characters

All existing functionality, such as creating new lists, dragging to rearrange them, or moving cards between lists, is preserved. Groups can be toggled on and off by clicking the extension either in the drop down menu or by clicking the icon when pinned to the toolbar.

This extension is based on Swimlanes for Trello by Jeff Yaus
