Nicknames
I have three networks in different homes. I named them all the same and use the same password for all of them. This way when I go from one place to the other I do not need to setup a new network for any device I bring in. They recognize it across the board.
The problem is that since they are all the same (save for some capitalization in the network name) I cannot tell one from the other without looking at the devices in the network. This is a problem if I want to make changes to one of the networks. Of course, it is only inconvenient but not a disaster.
It'd be great if each network had a NICKNAME that was not the network name. It doesn't seem that this'd be a big deal to implement and add to the software. Many other networks I use have nicknames.
