Score: 5.8/10 (Innovation: 4, Technical: 6, Documentation: 8, Utility: 5)

wsl-tray is a Rust Windows tray icon that shows WSL2 VM state, CPU, and memory usage, with a one-click shutdown and autostart option. It uses NtQuerySystemInformation to read vmmemWSL stats without admin rights and renders a custom Tux glyph for the icon. The polished README, tiny binary, and thoughtful engineering make it a nice utility for WSL2 users.

Target audience: developers using WSL2 on Windows
