Oh I don't know, I could see it being useful it it's possible to hook up with rtk-query or react-query, to prevent duplicate requests from multiple instances of an app that might be running.

Though I guess this might just trigger all the requests on all that tabs anyway. I suppose you'd have to add architecture to start one instance of that app as the 'controller' and then a way to pass off controller responsibilities to other tabs... which sounds like basically "step 2: draw the rest of the owl"

Since I just noticed this is an extension rather than a library, I think it's probably more useful for automating interactions with a number of tabs of the same page (but puppeteer or something similar would probably be a better fit for this also)

For cross-tab communications, there are better APIs, like https://developer.mozilla.org/en-US/docs/Web/API/Broadcast_C...

For user-driven automations, something like Tampermonkey would be way better (and safer, since they can be domain-limited).

I can think of no reason why a regular user would want to allow tabs to execute each other's code... that just seems like a setup for self-XSS attacks by people who don't know any better :(

edit: Sorry, re: the second part of your comment, I misunderstood what you meant. Like if you wanted to purposely script multiple identical tabs at the same time.
