The text box included in Power BI has very limited formatting options. The following items would make the text box more useful: -Bullet/Numbering -Spell Check -Strikethrough -Subscript -Superscript ...
Text boxes as they stand are not useful due to too few formatting options. Basic text editing formatting is needed. An example set of what I would expect to see in text boxes can be found in any of the other office applications when inserting a text box.
