I bucket Eclipse under "heavyweight IDE". I used to use it, plus the CDT plugin, for my C++ nonsense.

Then Visual Studio's Express and later Community SKUs made Visual Studio free for ≈home/hobby use in the same bucket. And they're better at that bucket for my needs. Less mucking with makefiles, the mixed ability to debug mixed C# and C++ callstacks, the fact that it's the same base as my work tools (game consoles have stuff integrating with Visual Studio, GPU vendors have stuff integrating with Visual Studio, the cool 3rd party intellisense game studios like integrates with Visual Studio...)

Eclipse, at least for me, quickly became relegated to increasingly rare moments of Linux development.

But I don't always want a heavyweight IDE and it's plugins and load times and project files. For a long time I just used notepad for quick edits to text files. But that's not great if you're, say, editing a many-file script repository. You still don't want all the dead weight of a heavy weight IDE, but there's a plethora of text editors that give you tabs, and maybe some basic syntax highlighting, and that's all you were going to get anyways. Notepad++, Sublime Text, Kate, ...and Visual Studio Code.

Well, VSC grew some tricks - an extension API for debuggers, spearheading the language server protocol... heck, I eventually even stopped hating the integrated VCS tab! It grew a "lightweight IDE" bucket, and it serves that niche for me well, and that's a useful niche for me.

In doing so, it's admittedly grown away from the "simple text editor" bucket. If you're routinely doing the careful work of auditing possibly malicious repositories before touching a single build task, VSC feels like the wrong tool to me, despite measures such as introducing the concept of untrusted repositories. I've somewhat attempted to shove a round peg into a square hole by using VSC's profiles feature - I now have a "Default" profile for my coding adventures and a "Notes" profile with all the extensions gone for editing my large piles of markdown, and for inspecting code I trust enough to allow on disk, but not enough to autorun anything... but switching editors entirely might be a better use of my time for this niche.
