Monitor context window usage and output in console

The statusline feature is incredibly useful. I even created a script — statusline on GitHub — to monitor context window usage in real time.

It would be fantastic if this were built directly into Claude Code itself.

Some frameworks built on top of Claude Code, like SuperClaude, load a large amount of context into the window. Having a built-in way to see real-time usage would make it much easier for users to understand and optimize their context consumption

Any thoughts?
