Why not just use X?
Why not just use another tool like Obsidian, Notion, or Todoist?
Inbox is intentionally a dumb, frictionless capture layer. Those tools are great once you are ready to organize, but they invite context switching and backlog browsing. Inbox keeps a blank sheet and drops everything into plain Markdown, so you can move it into your main system when you are ready.
