Let's use sublime as an example. File. Open Folder. Select folder. It now shows a tree on the left. Now I want to change a variable, struct or enum name project-wide; there's no obvious way.
Also, Sublime doesn't do refactoring but VSCode totally does, given appropriate language server support which does exist for e.g. typescript. I have no problem believing that IntelliJ has more and fancier refactorings and code navigation features, but honestly I have never had a lot of use for anything more than rename, goto definition, find all references, and most importantly function/variable name completion, which all work great in VSCode.
