The infinity symbol doesn't bother me; what I don't like is that the information about the number of open tabs isn't available anywhere else. As a result, I have to run a script on the browser console on my desktop.
Also, I'm not sure if it's just my old iPhone X, but I've noticed that when I have 100+ tabs open, the app crashes more frequently.
I first heard about Shazam when I worked in a project to integrate Shazam API to Hello Moto J2ME app back in 2007~2008.
And it was amazing to see how they were able to move to the smartphone world so gracefully!
