@jhgg - Can you speak on any plans to offer some sort of positional audio functionality in the Discord API? Perhaps you can use the existing game hooks available for the Mumble API's positional audio system? Being able to fully ditch TeamSpeak would be a big win for my group, and a disruptive move for you guys.
Additionally, I love just about everything about the Discord client, but I would like to see voice quality improve to the level of where I remember Mumble to be, though admittedly I haven't used that in a while, though remember it to be fantastic, barring network hiccups. I also have an issue, both on the desktop client and the Android one, where @notifications come in 'late', from minutes to hours. Furthermore on the desktop client, the notifications aren't always shown on screen, as a timer seems to be started before the pop-up is actually drawn, and something like the accompanying HDD activity during that timer lifetime can cause the timer to expire before the notification is drawn on screen.
