I wondered whether there is any way to control the font size of the text under the "outline" pane; as far as I can, it is not part of the option that are configurable in the "theme" file, which seems to only control the appearance of code in the source pane (but I could have definitely missed this option, in which case it would be an easy solution and would not require the kind of hacking I describe below).
So I dug in a bit by using the nice "inspect element", and it wasn't too long when I found that I can change the font very easily by changing a member of the .GD15MCFCMDC class:
basically by changing font-size to something like 10pt the outline becomes visible for me (I'm working at a very high resolution and my code font size is 14, so anything below 10 is hard to read).
I wouldn't mind doing it once, but the problem is that I need to do it every time that I quit and re-open RStudio, and I usually have multiple of those open. Plus, I have a feeling that what I'm doing is indeed a hack, and not the way this feature, if exists, is supposed to be used.
So it all boils down to:
- Is there a simple way to control the font from within the editor?
- If not, can I control it in the theme file?
- If not, can I change the class element permanently so I will have a persisted font definition for the outline pane?
