+1 to this one! It would be a very helpful improvement.
I’m missing this feature too

This would be great! +1
Could be a 5-way toggler:
- UPPERCASE
- lowercase
- Sentence case
- Title Case
- back to original
And of course not only for the [A-Za-z] range, but according to Unicode rules correctly for all languages.
Hee hee. 
Or we’d need even more hot keys.

‘Back to original’ is tricky. You’d have to persist the original state forever.

Right. Maybe undo is good enough.

Is there some workaround, until this feature arrives?
A workaround (with inline LaTeX) has been found here: Subscript - #2 by s-kyy
If you wanted to do CO2 with the 2 in lowercase, for example, you would write $CO_2$ or $CO_{2}$
For uppercase you’d do $CO^2$

It looks like the Text Format extension for Obsidian can format the selected text into UPPERCASE, lowercase, Title Case, etc.
