For several years, this has been requested by numerous people. Your bug fix list claims that it was resolved / fixed, but it was not. I do not believe that LibreOffice developers understand the issue / need. The formula bar needs to allow for a LARGER font, just within the FORMULA BAR. This is not something which can be changed by using "View / Zoom" within menus, within LibreOffice settings / preferences, or within the OS settings / preferences. As my formulas tend to be quite short, I do not need the large amount of calculation space available in the FORMULA BAR. I DO want to be able to see and use the FORMULA BAR more effectively, with a LARGER font.
Please follow along in bug 153727 When that gains dev traction issue will be resolved there. *** This bug has been marked as a duplicate of bug 153727 ***
