"through their eyes" would be such an amazing #nostr discovery feature. Click on someone's profile, and view nostr through their eyes.
Incredibly simple to implement too. (Works already if you log in with someone's npub, but nobody does that.)

Kieran has it working on Snort already but it’s not enabled because it has issues dealing with multiple accounts.
You can add anyone's feed to your feed lists on Primal to view their feeds directly
Primal has this and it's great. You can go to someone's profile and say follow this feed.
Then on your feed you can select "Gigi's feed# Different name but same concept.
Hah, how have I not thought about this, the big thing here is that you become exposed to another filter bubble, quick and easy. Which is dope.
Wen GunnSight?
essentially a much easier and more user friendly implementation of kind3.xyz by nostr:npub1l2vyh47mk2p0qlsku7hg0vn29faehy9hy34ygaclpn66ukqp3afqutajft
Just having the npub doesn’t work imo, you want to experience “through X’s eyes but be effortlessly able to interact with what you see” that was the idea behind building kind3.xyz although I recognize that the friction of having to go somewhere else makes it too cumbersome.
But yeah, this concept is so powerful and novel, I’d like to see it more broadly supported
nostr:npub12vkcxr0luzwp8e673v29eqjhrr7p9vqq8asav85swaepclllj09sylpugg is providing that through ability to show feed of given profile.
Nostur has this feature as a button on profiles called “Show Feed”. It then pins that person’s profile pic to the home feed so you can see notes from everyone they follow.
So cool… 
A masquerade feature.
I use this feature (provided by a module) a lot within Drupal projects to check / test user permissions within the CMS.
I like it.. I just know at least a few of you would do this to me though:
Nostrudel ninja has this. Also planning to do it on nostr:npub1gp4xzpmluelsakjtayc4wtzj97fhj5kakqjvsannu00xkdlf4x8s0xdqyq
I spend more time on your npub then my own 😉
Nostur ftw 
Being able to add a user to a list in-app without having to go to listr.lol seems like a super power.
Yes! Seems like most of these features are available from the users post and not particularly their profile, however there are separate features from profile and many more from settings.
It’s like a nostr playground for me atm.
For the blind (love the article feature) 👀 https://video.nostr.build/25260e82b6eec4fb21139e6b656a4d8deb437cb3d847cbc73dcc49cfbf53c736.mov
