This may already be possible and i'm just unaware of how to do it but I would like to see an option to be able to back up just QoS settings and restore them.
Example of why I would want this feature is toastman's QoS settings.
I would like to be able to go through this set-up only once and then post the config for anyone who would want to load it up. I think toastman would agree that this would be a good idea because then he could just post these files as well for people after he updates his configurations and people could just load them right up. (Obviously not with his naming scheme he has going)
Also if anyone has special QoS setups for particular reasons they could share them with others that may want that set up as well. Kinda like the way people do with Themes right now.
Being separated from the rest of the config makes it so that people can just get the portion they want and not have to worry about re-doing the rest of their settings.
Eventually it could be set up to do this for multiple sections but I think the QoS section is the biggest draw for this type of request.
