RStudio desktop supports font ligtures now. But after I install Fira Code fonts in my Debian laptop and tried to enable it in RStudio -- Global Options - Apperance -- Editor font, I cannot find Fira Code in drop down menu. I tried searching for anyting I was missing in vain. Also, RStudio team said settings are now stored in ~/.rstudio, still I didn't find where editor fonts setting were.
I am sure Fira Code fonts are properly installed as I can enbale it and see it working in other applications (eg. kitty terminal).
Anyone know why this is happening?
