Is there a way to add code folding arrows next to round brackets in RStudio? For example, in the picture below a can collapse using the little arrow next to it, but no arrow shows up to collapse b. Is it possible to make those round brackets collapse without having to select the region that needs to be collapsed?
I'm especially interested in collapsing sub-brackets, which is already possible with the braced (as shown in c and d).
I have found that I can fold anything by selecting it and typing ALT+L, however, that can be rather tedious when needing to fold in a document with many brackets. Therefore, I am looking for an option to make the () brackets collapsable like the {} brackets.
