Option to Set <any_color> Notifications as You Feel Fit

So we have red notifications already for mentions. It would be nice to be able to setup more color notifications for new message as well.

For instance. If you have sound on specific servers/channels you know which servers/channels to check, but not exactly which one it is. If you could setup a color notification for a server and/or channel let's say a specific channel and it would be applied just as the red notification would do, but just another color. Then you can easily find where the sound notifcation went off instead of needing to look through the servers/channels you have enabled the sound notifcation for.

Also to seperate the red one from the custom one, you could make it so that the custom one's dot is in another place on the server avatar so they don't cover each other if you'd happen to get a mention from the same server as well.

And you could have the color selector that roles have, but also when you set your own colored notification.
