I understand the reason you felt compelled to build this app, but doesn't favicons do the same for us, mostly, help, identify same subdomains and organize them? If this could be made more advanced like categorizing based on switching patterns, as a developer I need to switch between multiple tabs to work and verify content usually, or control some video I'm playing, this would fit better in my daily usage. Just a thought.
