Grant UNIQUE Text Color Theme for user-declared 'Custom Variables' in Text Editor, probably as a user-friendly Displaying Option (default or not default?)

Hey, folks!

I'm not a Programmer, but I still enjoy studying the concepts and can make basic, handy Python Scripts in Blender.

However, let me say, I find shockingly frustrating, that the Text Editor in Blender, is not capable to dynamically make a clear distinction of Variables' categories in current use; for instance, between which might be considered 'Default Variables' (if that makes sense) and 'Custom Variables' (i.e., any free-to-use String given a relashionship through a scripted equation in order to become a Variable)

I think it would be a very user-friendly addition, as a Togglable Option.

I'm unsure, but maybe, this feature could also be expanded to other Scripts-Displaying Editors, such as the Python Console, Info...?

I just think it would be a fundamental resource for learning and making Scripting, Coding and Programming more accessible and efficient to the majority of people. I'm not sure if I've seen this feature elswehere and to which extend of 'smartness', but I believe I've seen something close to that.

I believe it would be very cool if Blender made this kind of feature possible --somehow.

Here is a visual example (maybe it's Code-incorrect, but I hope everyone can grasp the overarching idea): Note: the pinkish Color is just a random proposition of Color, there might be much better default Thematic choices.

Thanks for the attention!
