If you want to hide a task from a board so that it’s not taking up space (for example, if a task is finished) and you don’t want to completely delete it as you might need to reference it again in the future, you can always archive the task.
Archive a Task
There are two ways to archive a task in Rindle.
The first way is to click on the task you want to archive. Select the vertical menu in the upper right and click “Archive."
The second way to archive a task is by hovering over the task itself and clicking the pen/paper edit icon. From there, click the bin icon to archive.
View or Restore an Archived Task
To view a task that has already been archived, first navigate to the task's original board.
Click the ellipse menu in the board views navigation at the top.
To restore an archived card, click the “Restore” button beside it.
