Rstudio: enhancement: colorize/highlight/gather all TODO, FIXME or IMPORTANT comments

[verajosemanuel]

Usually, for smaller projects the common behaviour is to use a lot of comments in the code. Not every project needs complex issue tracking and big code control software. Besides, sometimes is quicker to look at the code.

Keywords as TODO, FIXME, or IMPORTANT are very useful to remember some days after you wrote a lot of code what to do next or as a guide for the coming days in the same project.

The feature should highlight specific words (TODO and such) in a way that can be easily detected looking at code with no need of using the integrated search.

Take ¨Better-comments¨ VScode Addin as an example of this feature:

In a step further, all TODOs could be gathered in a table or document to have global view of pending work. Take ¨TODO-SHOW¨ Atom Addin as an example of this feature:

If keywords TODO and FIXME are written as the first word after the comment symbol # in R code, they are highlighted.
At the moment, R package "todor" finds TODO, etc. comments and collects to "Markers" tab.
Does the package fit your needs?

Yes, package TODOr is ok, but this feature is a good one to be included out-of-the-box
Thanks

If keywords TODO and FIXME are written as the first word after the comment symbol # in R code, they are highlighted.

I think this is already quite useful but I am trying to customize this in my theme.
I am trying to changes the .rstheme file so the # TODO has a yellow background and can be found much easier while scrolling to the code.
The code highlighting regex already has the keywords TODO|FIXME so this should be fine. The Problem is the TODO belongs to the object .ace_keyword.ace_operator. This object also includes (, ), $, =, *, +, ~, / and <-.
Obviously I don't want to change those. I seems that there has to be a new object just for those two. But I don't know how to implement this.
Also it is hard for me to understand why TODO is classified as an operator?
