I think most of us have used any advanced code editor sometime, namely Atom, Sublime Text, VS Code, Brackets, ...
I personally love Atom, I have already mastered it and with that I have been dealing with its weak points: performance with big files is the biggest one IMO.
Browsing and researching I have found that most advanced code editors (named in the first paragraph) are web-based, programmed in HTML, CSS and JavaScript (or variants of this one, which are almost the same).
Several people recommended me to take the step and move to EMACS or VIM. I really have no that amount of time to start learning these, and I am not really interested.
So the question is the title: Is there any advanced code editor that is programmed in a higher performance language (C++, Rust, ...), available for Windows, Linux or Mac with almost the same good features as the mentioned ones (open-source would be great)?
Thanks in advance.
