My browser's target is mainly two - devs and sovereign individuals.

devs: Multiple keys, easy switching would be useful when developing app in the localhost using vite dev server, etc. The typical user is me :D

sovereign individuals: Currently exploring though, the aiming vision is increasing the places to apply self-custody for individuals and ensuring humanity on AI ages.

I feel like both of two characteristics are similar (and both are minority!). Anyway, on these way, choices are many, decisions to make are many, so learning needs much.
