In a LibreOffice Impress presentation (Version 126.96.36.199 on Ubuntu 16.04), when I click Insert -> Object -> Formula, I see a visual toolbar that lets me add elements of an equation such as fractions etc. However:
- The inserted formula is in a very small font (18 pt), and I do not find any way to enlarge it, neither within the formula editor nor outside it. Outside the editor, I can enlarge the font of the box, but it has no effect.
- It is very cumbersome to insert formulas through the visual editor. Is there a way to insert formulas in a plain text markup, like in Writer?
