In Dart you can save any particular set of tasks as a view so that you can come back to them later, even if that view includes tasks from different spaces and dartboards.

In Dart, Views are different from Layouts (List, Board, Calendar, Roadmap). Think of a View as a way to see tasks across more than one single dartboard.

You can access views from the lefthand column of your dartboard:

The basic view that Dart has by default is called My Tasks (also at the top of your left-hand column in Dart).

This will show you tasks across any dartboard. You'll be able to see all of see your tasks across every project listed on the left and the associated space/dartboard icons in the dartboard column:

Whereas, in Board Layout, you will see the space/dartboard icons at the bottom of the task, underneath each title:

If you would prefer to make your own customized View, simply choose “View” from the left-hand column of your dartboard. This will show your list of customized Views:

To add a new View, simply click on the “+” button on Views.

Name your View whatever you like and customize it to suit your purposes. Once you've created a View, you can do a variety of other actions, including exporting, replicating, and favoriting.

You can even manage sharing. Choose between keeping your View to yourself, inviting specific team members, opening your View to the entire workspace, or even making it public (so that anyone with a link can access your View):

You can also filter and sort when you are in "My tasks" or any of your "Views." You can find your filter and sort options at the top left of your view. Note that, in My tasks, Assignees will always show as Current user:

You can also customize search parameters and save those as a view. Simply click on the search bar at the top of your View layout and enter in your desired parameters. You'll then see a Save view icon at the top right of your screen:
