Nice work! I have actually been working on something similar.

Main differentiators: - Based on tmux, so you can connect to a persistent session from multiple devices - Responsive, resizes sidebar based on mobile/desktop client connecting - Status indicator icons for major LLM CLIs (needs input/thinking) - Completely built into tmux, emulator-agnostic - Supports grouping of windows - Supports color and emoji-coding windows / panes / window groups - It's higly configurable using yaml
