I use logseq for note keeping but I just want the text editing experience of vs code.
I'm not sure why they all roll their own editor. Can't it be a plugin?
1. Editor as in a complete program that is VScode and everything it entails.
2. Editor as in the actual text editing experience with syntax highlighting, code completion, etc.
You are likely thinking about the first type. Where the person you respond to is talking about the second one. The experience of editing markdown in VScode is a very pleasant one so I can see why people would want that editing experience in other markdown based note apps.
This way I context switch completely away from code.
Also it annoying to swap workspaces and keep the up.
I can see how having the environment be at least cosmetically different might help though. I feel like there must be a good enough solution to that, I'll have a poke around
There are multiple reason, like editors having too much of their own baggage, or not being meant to be used as a foundation for a mature app. But I guess mainly it's a matter of licensing, and building your own editing-experience.
VS Code is for plaintext, while obsidian has deep rich-text-handling. It's probably not that easy to combine both flawless and still supporting all the plaintext-editing.
For actual coffee editing, there is also https://github.com/sunxvming/obsidian-vscode-editor
