- Cross-platform support (Windows/Linux) with Windows Updates and Winget
- Added dependency confirmation workflow and refresh token authentication
- New screenshots: History, Live Operations, Windows Agent Details
- Local CLI features with terminal output and cache system
- Updated known limitations - Proxmox integration is broken
- Organized docs to docs/ folder and updated .gitignore
- Probably introduced a dozen bugs with Windows agents - stay tuned
