Respect the desktop environment's default fonts

I’m dependent on serif fonts for accessibility reasons. Ultimately it’s best for me when all text on my computer screens is in the same font. (At this time I’m using Gentium Plus.)

So I wanted to look into how to make it the default in Calc. And the accepted best solution seems to be to make a template and start new documents from that. But that doesn’t work when I start a new spreadsheet by doubleclicking on a CSV and going through the import wizard, which is how I create most new spreadsheets.

That got me wondering: why does LO set its own default anyway? Why doesn’t it just respect the default fonts I set in KDE System Settings?

If you don’t get the font you want on import, then right click Default in the Cell Styles pane of the Sidebar, select Edit Style and set the font there. All cells in the spreadsheet will then use that font (except where you have manually set the font for some cells).
