This was one of the most painless installs ever, just pip it and run it. Done! And of course open source on Github. Great job, thanks!
maybe an installer instead of the standard linux way of forcing you to know things you don't really need to know?
EDIT: Popping up an entire webview from Tray doesn't seem to be easy. But creating a menu is very easy. I might do a simple clone of hackertray to Windows :)
