So there are things that i think are missing or just would be cool features.

One cool feature would be to be able to link your Spotify/Itunes or whatever music app you use to your radio. Much like what GTA IV/V did where you import your own music and you could listen to it.

One thing that i miss is withdrawing weapons and not being able to see them on your back/ hip. Even the Deathclaw gauntlet and the knuckles don't show up on your hand. You could do it in FO3, NV and even Skyrim. So why not FO4?

those are what i have, maybe you have something or think mine are stupid, but why do you think that?
