Multirow is a Blender add-on from flakmoppen that makes it easier to put multiple rows of text into a TextStrip. It handles text strips with line breaks, and works across the Sequencer, Text Editor and Blender's user interface.
Version 1.0.1 introduced an addon preferences class, moving variables such as the default text name and custom properties into it. It added a text data ID to more accurately track text data, and uses that ID to clean up or reuse old text data when needed. A prompt now appears before creating new text data if the last text strip edit was terminated wrongfully. The script was streamlined, resulting in some changes and efficiency gains.
The add-on is compatible with Blender 4.4.3 and newer, requires no special permissions, and is released under the GNU General Public License v3.0 or later. It's a small download, around 4.3 KB, and is listed here as free.
