The title case isn’t accurate. As it also capitalizes:
- articles (such as “a,” “an,” and “the”)
- conjunctions (such as “and,” “but,” and “or”), and
- prepositions (such as “at,” “by,” “of,” “to,” and “on”).
IMO the better naming would be “Capitalize”? + Figma can consider adding “Title Case” and “Sentence case” options separately.
