What would make a lightweight browser your daily driver on Android?

I've been building Agogo, a tiny Android browser (system WebView, a few MB) with an ad blocker, userscripts, a BYO-key AI assistant and full-page translation.

Curious what makes people switch browsers on mobile:

• The one feature that'd make it your daily driver?

• What made you leave your last browser?

• Something no mobile browser does well yet?
