Here's a quick one. If you're using Visual Studio Code as your Markdown editor and work with larger documents, such as a daily journal, VS Code's default behavior of showing breadcrumbs might be a performance drag.

To turn off header-level breadcrumbs when working with just Markdown files:

  1. View > Command Palette > the JSON User settings > Preferences: Open Settings (JSON)
  2. Add this setting
    "[markdown]": {
        "breadcrumbs.showStrings": false

If you want to disable breadcrumbs for all languages, use this setting:

"breadcrumbs.enabled": false

Happy writing!
