Before actually implementing the backend to handle wlanX and ethX and
the new network device naming scheme, I had to plan how the GUI should
look and work. This means, netman is still unable to handle devices
other than wlan0 and eth0. The backend will have to be modified to
enable it to handle such devices, and that takes time to do properly.

I learnt it is more efficient for me to let a day or so pass, as that
enables me to think of better algorithms, and effectively, I end up
coding more efficiently as faster. It is how my mind works: if I give
it time, ideas come with far less effort.
