Qol improvement to search

[t3dium]

It took me a while to figure out why the search wasn't working, i think it'd be good to automatically refresh the channel list when joining a network for the first time & persist this info, otherwise it always reports 0 results being found until the user manually clicks on the refresh button

Sure, it is reasonable.

But currently, I have no enough energy for this project. Is anyone willing to help with this feature?
