I have a number of boards and want to see all my outstanding tasks. Is there one place where I am able to do this, without having to go to each board individually?
This is now available here and very useful.
Just visit https://trello.com/my/cards, or click the ‘Cards’ link in the sidebar. Trello sorts cards by board then by list, so cards on leftmost lists will show up first.
The answers in this thread might be helpful: Is it possible to view cards across projects by due date on Trello?
The first answer points to a third party site Trello Calendar and the second mentions a card on the Trello development board discussing a similar feature.
Hope this helps.
