Just a simple little one … this could help when a PC player bounds up to a PS4 player and just starts blabbing on … no amount of ability to speak English can help with a software keyboard.
Equally, if someone’s just playing with a controller on PC, they might wanna put the icon up … could just stop a talkative person (like myself) wanging on which might make the other person a little frustrated either by not wanting or being able to reply easily/at length, or whatever. … not to mention the anxiety they might feel about looking rude.
For the record, I never think that someone that doesn’t respond is rude. However not being able to (or maybe not feeling like it) would certainly make me feel like I might be perceived as rude … so I thought I’d mention it.
Anyway, just a thought … leaving it here, not subscribing to the thread, as I don’t need to debate a suggestion.
