Hide one item, or hide it only on phones

In the editor, click the item (for example one feature in a list). In the small bar that appears:

• press the phone icon to hide it on phones only, or the computer icon to hide it on computers only (press again to bring it back);
• or press Hide to hide it everywhere.

Only that item goes. The rest of the row closes up by itself: the items left spread across the row and no gap or stray line is left behind, on computers and phones.

Hidden items are listed at the top of the editor under Hidden items. Press Show to bring one back.
