Customizable statusline - context % and usage #2342
Description
Describe the feature or problem you'd like to solve
A live context % in the statusline would be genuinely useful and is a natural fit for the existing statusline that already shows remaining requests.
Proposed solution
Hitting the context window is annoying, and having to monitor your context (and usage) which is hidden behind a command (/context or /usage) can be a hassle.
Having this information directly at hand, in the statusline below the prompt box would be a boon.
Example prompts or workflows
Example image (from similar tool):
Progressbar (emtpy in screenshot) shows progression inside context window.
(Hitting 100% would trigger compaction or data loss.)
Other info on line: usage / usage limits. (This feature is partially available in GitHub Copilot CLI already.)
