Thats messed up if u can do this without consent of whoever you are tracking.
If you are gonna do this the right way, with consent, there's probably free apps that can do this (not sure if there are any privacy friendly ones though, but I believe iphones have a tracking feature that's free).
$10/month is scammy, but they know their target audience ig (abusers probably, like you say).
Yeah pretty sad. It would be a much more useful feature for me on mobile.
On desktop, I usually just create a new window for different types of stuff.
No easy way to organize my infinite tabs on mobile (as far as im aware).
Chromium browsers on mobile do this, but it's also a bit weirdly complicated/frustrating to work with at times, I hope of Firefox get to it, they can make it super simple.
