Uhh, I love answers like: dont hit the key. That is no solution.
The concept with the perception is nice, I agree. But to hold down the alt key to see this ugly nameplates after exploring an area or better to hold down the key the meantime is so annoying.

I didnt play a lot in the beta/early access and have no experience. But I hope the game is so much fun like the forerunner dd/bd and I like to spend a lot of time to it, want to have many playthroughs
and like it to forget anything here and some crafting materials there. To be better the next time I play with other characters.

But a keybinding or an option for that might be the best solution I thought
