Re Enable first time setup

The only way I know how the first-time-setup wizard will come up again, is to do a hard reset with:

mv /storage/.kodi /storage/kodi-bak

but that will remove all your installed addons again, because it's like a factory reset. So connecting to wifi networks has to be done manually over the LE settings after you have installed your addons.

This would make connecting to wi-fi for example easier

In what way? You can enter the LE Settings addon, and see which other signals are there.
The connect process isn't that much difficult.
