* Why can't I quickly and immediately flag my intent to speak? Once you introduce lag into a conversation (and _every_ video chat conversation includes lag), you can't get away with "let's just be unmuted and hope for the best".
* Why can't everyone in a chat see participants in the same order? How can we truly feel like we are speaking in a virtual space together when we do not share the same view? This one is the most frustrating since it has the greatest impact compared to how easy it is to implement. It is hard to overstate the benefit of having a consistent shared experience.
* Why can't I tell at a glance whether I'm muted or not? Why do I have to find the mute button every time? Everyone has a keyboard, why are we avoiding it like the plague?
* Choosing the correct input/output sources is one of the most common source of issues. And yet, we continue to hide it behind confusing settings. I've only noticed Discord get the memo and let you adjust sources straight from the main screen.
