I'm surprised by that. If you mean the options at Tools | Options... | LibreOffice Calc | Calculate | Case sensitive, doesn't this apply per user and thus stick not only between documents but between LibreOffice sessions?

How can I save this option permanently so I don't need to set it over and over again?

If it doesn't stick - and if this option is, as I imagine, saved in the user profile - you might want to wonder if your user profile has become corrupt. If you close LibreOffice and delete or rename the profile, LibreOffice will create a new, clean one next time you start it. If you then set the option again, does it now stick?

To clarify: I need the string comparisons of IF() to be case sensitive:
'if(a1 = "x"; ...)' is, of course, different from 'if(a1 = "X"; ...)'.

Why would anyone make them not case sensitive unless explicitly specified, ...

I suspect those who prefer the other option would ask the opposite question! If you are looking for references to dogs, you might want to find "Dogs are friendly pets" as well as "My dog's got no nose".

... and how do I specify case sensitiveness per formula?

If the option is, as I suspect, per user, your spreadsheet will go wrong if you need to change the option for another document, if a different user handles it on the same computer, or if you exchange it with someone using a different computer. So you are quite right to identify that building the requirement into your formulae and not relying on options is the reliable way to go. And it's quite easy: the EXACT() function comes to your aid. Instead of using
This will match "X" but not "x" irrespective of the option setting.

I trust this helps.
