Formatting Rules change how item titles look across your whole organization, based on the item's status. The first rule, Strikethrough Style for Statuses, marks work that will not be done. Pick a status such as Cancelled, and every item in it shows its title in red with a line through it, and an X on its item icon.
Without it, a cancelled item looks like any other item, or like finished work when its status counts as done. With it, nobody mistakes cancelled work for open or completed work, whichever screen they are on.
Configure Settings → Organization → Formatting Rules. The page needs the Configure Organization permission (MANAGE_ORG_CONFIGURATION), held by the default Owner and Admin roles. Changes save as you make them; there is no Save button.
Under the Item Style heading:
While the rule is on, every work item whose status is in the list shows:
This applies wherever an item's title appears: the Items table and every list built on it (My Work, board list views, an item's child items), board cards, the Map Value view, Track Progress (the name column and the label on each bar), the item drawer header, search results and the Cmd/Ctrl + K search, relationship lists and item link previews.
