First, thanks for your tool! It has greatly improved my dev workflow.

Two actions that k9s offers when visualizing logs are the ability to clear logs and add a marker at the current position. Both are pretty useful for debugging services and removing clutter, and I’d love to see these features in process-compose.

Thanks!
