Ability to turn a list item into a heading
I'd like to propose the following behaviours for turning a list into a heading:
-
if you have made a selection range in a list spanning multiple items, offering to turn it into a heading should remain unavailable. -
if the element is enabled, the item that was selected should be turned into a heading, and the items preceding it and following it should be split in new lists. -
if above is prohibitively complex to handle, turning a single element list into a heading should be made possible.
