Trello re-open closed board in Android app

I agree with your friend about not dividing up into separate boards by type of job.

With your examples such as 'Design ideas' etc, I think they really do fit naturally within different lists on the same Board. It's exactly the sort of usage that Joel demoed in multiple videos about Trello.

The only thing I can think of, to help manage very long lists, is to use Trello's Labels system to put categories on cards, and then use filtering. You should definitely give meaningful names to the default labels.

I wrote up some tips on how to use labels recently.

Having said that, fairly early on the Trello on Trello board got huge, and eventually they reduced the scope of it. So it's does seem to be a well-known problem.

The Trello guide is a little bit out of date. If you are the owner of a board, you can rename it like so:

1. Click the board title (or the "Board Menu" button)
2. Click "Profile"
3. Click the name of the board (at the top)
4. Type in the new name
5. Click Save
