thanks for the feedback!!
> I'm currently just a bit nervous with automated channel closures
no need to be nervous! the worst thing is that you will have to wait a few days until your sats are available as onchain balance
BUT with the Alby Cloud subscription our plan is that it's taken care of and you'll always have a channel to receive. Even if it closes a new one will be opened for you. So no worries.
> we need to keep the web app opened
That is only the case if you use the Desktop app. If you use the a cloud or pi version then you don't need to keep the web app open. The node will keep running in the background.
