I meant as a browser for mini web apps? They support nip07 which makes it extremely easy to test out a lot of web apps without the inconvenience of bunkers. They have gone a long way from just a messaging app

I would never insert my nsec in any app that has a browser inside of it. Ever.
You could test it out with a test nsec to actually see how it works. We all inserted our nsecs in amethyst before amber became the norm. They are actually moving in the right direction
They support amber as well. 
Cool, then you don't need the inner browser. You can just run it on a regular browser if they support nip55
