I agree with all of this, I earn sats in a few lighting wallets, and all is invoiced over into my “main” wallet by hand so that I may spend and receive from one place. (kinda like checking the couch for coin then putting them in your pocket with the rest)

If you must send from different wallets how much easier do you need it than the handy list attached?

As for bringing liquidity into the lighting network, I have only relied on custodians to provide liquidity into the network like bull Bitcoin or Wallet of Satoshi. My experience in finding a way into lighting has taken more time and effort compared to actually moving & spending.
