I realise that the Network Tab pops an error if this is the case but it still writes it in gui.network.conf. So if you click away from the tab and forget about it then when you reboot the system it will be broken.

Say you want to swap the "External interface" eth0 with the "1st LAN Interface" eth1, resulting in EXT:eth1 and LAN:eth0 ... all interfaces need to available to swap interfaces around.  During the selecting process there could be interfaces used multiple times.  Our PHP POST web interface offers a static state of menus between requests.

I suppose there could be some javascript real-time warning ... and could be annoying.
