Hi @JVSKGardening . Your idea for folder‑based readable line length setting is good — however other settings as well could be tied to different folders. This could be a feature in Workspaces. See my comment in other thread:
You could also use xlsx. file links inside your notes. When clicked you would be directed to Excel etc. Creating file‑links is documented at Internal links - Obsidian Help. You can also create file:/// links that doesn’t import the file to your vault. Creating file:/// links is documented in Drag and drop - Obsidian Help. By default Obsidian doesn’t support all file extensions but you can toggle
Settings →Files and links → Detect all file extensions
