I did give CLion a try when looking for an editor, but last I checked CLion required you to use CMake. Also, JetBrains has it all split up between different IDEs. I need on e that supports C, C++, Python, Cython, Makefile, TypeScript, SCSS, XHTML, Shellscript, JSON and XML in the same program. I also need a program that can do CMake and C, and a program that can do C# (including project management, building, tests etc), Batch script, PowerShell, Shellscript, Cake and YAML, preferably with the same UI. And it needs to work on Linux. VSCode is the only one I've found that can handle that.

That makes perfect sense. I used VS Code extensively for many years, and it kept on frustrating me over and over. I still use it on the odd occasion to edit a small script, but for larger projects, I prefer a dedicated IDE.
