Can I hide sub-tasks from the swimlane in the Active Sprints view?

[Samantha Sharkov]

Currently, they appear just as tasks.

You can change the "Filter query" of the board from this:

project = FOO ORDER BY Rank ASC

...to this:

project = FOO and ty[e != "Sub-task" ORDER BY Rank ASC

Basically, you show every issue type on the board, but "Sub-task".

If you go to "Board" -> "Configure" -> "Swimlanes", you can change the board to base Swimlanes on something besides Stories.  Sub-Tasks won't show up in the other options.
