Thank you! The Windows client is currently the primary focus. I'm working toward feature parity with the Linux client and hoping to have it available soon. macOS is on the roadmap after that.
Good catch on the GitHub link, that's a bug, I'll get it fixed. I'm planning to open source the client codebase and push it to GitHub in the near future.
I'll post updates on the site as clients become available. Appreciate the interest!
