That’s actually one of the main reasons I like Obsidian - that I can easily use vscode with it. Obsidian’s backend is just markdown files on the file system which you’re free to edit with another editor at the same time as you have Obsidian open (it’ll notice file system changes and update any open documents near instantly). I even have a plugin setup that when I hit a keyboard shortcut it executes the necessary vscode command line tool to open whatever I’m viewing in obsidian in vscode.
