It would be helpful to be able to change selected text to ALL UPPERCASE, all lowercase, Regular Case, or especially SMALL CAPS (if the font supported it), via the text dialog box (or perhaps via Paragraph or Character styles).
Yes, +1! It’s quite common to see the Title and/or Part name in all caps on the first page, but regular upper & lower on subsequent pages. I usually set up files so it is correct on the subsequent pages and then do page overrides on page 1, but this would allow for that process to be automated.
IIRC Daniel has spoken of the Team’s desire eventually to bring rich-text features to Dorico Text. I would hope that such case capabilities would be part of that process and that the rich-text features would be available for Text Frames as well as Text Fields.
