Column reorder ability

[godlev]

The column status (offline/online) is the in the very right of my screen and the name of the device is in the very left this makes it hard to quick check which devices are online. If we can reorder columns will make it easier to move the status column to be first next to the names and see quick overview. Additionally offline devices can be set with light red background row so they can be easily distinguished.

Unfortunately, this is not trivial to implement. I understand the need for it, but it is a very low priority for me. However, I am open to pull requests
