Device Specific App Settings

I was thinking about disabling images on certain devices but still want full experience when I'm back at my desk.

Also, this probably should be in another feedback but I thought it may help if this gets taken into consideration while device specific app settings are developed.

It'll be great if I can mute certain channels on the device level. That means, I still see certain channels having unread messages when I'm on my PC but I won't be seeing it on my iPhone for example.
