I find people doing remote work constantly missing big parts of information that is passed around verbally and doing extra work / being less efficient because of this.

We already use chat rooms, individual chats, tickets, video conferencing, email, dashboards, whatever.

But sometimes the bandwidth of just sitting with someone and looking at a problem together is so much higher that you can solve big issues in a very short time.

I think some psychologists could study this, it's right up their alley - what is lacking in remote co-operation devices. I personally think it's partly that you need to see what the other person is looking at and also you must be able to observe their body language. A way to do "Look here, this is important in about 0.1 seconds." But I have no evidence.
