[Mobile] Unread message indicator on hamburger icon

Very similar to the unread mention indicator (red #), I think a small white dot on the lower right corner of the hamburger icon would be very useful.

Currently, to see if you have unread messages, you have to open the channel drawer. I often leave my phone on my desk and idle in one chat, so I have no way to see if I have unread messages in other channels without manually checking. This fits within discord's existing design, re-using the white dot that appears next to servers and channels.
