It'd, sorry about that. Ya i understand how it currently works, but that doesnt answer why one couldnt have increased security by having a lightning node which could pair with say a ledger to require the hardware device to sign for any on chain transactions whether its sweeping funds out or opening new channels. Doesnt seem that would would impair locking funds into lightning channels ( once theyre in lightning doesnt matter how you signed the transaction) and would allow one to have funds sit in the lightning node's wallet in the most secure way.
