This is much better ergonomically than any similar extension I've seen - using a complete tab rather than cramming a thousand UI widgets into the extension popup was an excellent decison. Legibility is king (or queen).

I think the 'how to we make money' section of https://www.one-tab.com/ might need updating. It claims there is no plan for it to bring in cash. But then the 2022 update adds "We're full time on it now", which surely (unless they're very rich) implies the opposite. Which would be fine, but probably needs clarifying.

That's just a minor nit though. A very useful extension, well implemented.
