Text clips
Text assets can be created from Project Viewer (Ctrl+T) and inserted more than once in a timeline. New text sources start with an empty editor field.
Editing a selected timeline text clip updates its text and its reusable Project Viewer source without overwriting other independently edited instances. Editing a Project Viewer text source directly updates that reusable item and any existing linked instances that still contain its previous source text.
You can use the selected clip's primary Edit action in Inspector or edit a text source from Project Viewer's contextual icon. Unchanged edits do not add unnecessary undo history.
