I don't mean to be snarky, but what's the purpose of apps like this? Notepad.exe is 227 KB, runs instantly and flawlessly on even ancient environments, and gives all the basics. If you need something more "Power User," Notepad++ gives some language-sensitive formatting, tabs for easy switching between files, and plugins for custom use cases.
If you need something more specific to a given language, that's an IDE, not a note taking program. If you need to write something with a bunch of rich formatting, that's a word processor, not a note taking program.
The point of a note taking program is to be as blindingly simple, fast, and reliable as possible. It's the software equivalent of grabbing a scrap of paper (or maybe a little flip notebook) and scratching something down before you forget it. All this complexity defeats the purpose. A 200MB Electron app with web integration definitely defeats the purpose.
For the curious and lazy, this is what it looks like: https://files.catbox.moe/kcelmg.PNG. Note that this was after I clicked off a large, complex dialog nagging me to create an account and sign in. Already this looks way too complex for my taste.
Why are people so endlessly fascinated with forcing everything on the cloud? I have txt and rtf documents from decades ago that have survived through backup after backup. Meanwhile, if this program's servers go down tomorrow, tough luck.
