A Gallery view would make a useful addition to the Time, List, and Board views. In the Gallery view, tasks would appear on cards, just like the existing Board view, but without constraining cards to columns. Board view is good for workflows. Gallery view would be good for filtering and browsing.
The important thing to realize is that tasks don't always get done in order, and some don't require a workflow. A reading list is one example of a use case in which I might want to filter and browse tasks in a gallery view. Choosing the next blog topic for an editorial calendar is another.
The screenshot shows an example of the gallery view used in Airtable. This example happens to show recipes—another example of 'tasks' I might want to filter and browse.
