You mentioned Knots does not support connecting Sparrow to it. Not really a big deal since the wallet functionality is there more for historical reasons and its best to disable it anyway and use Electrum server to connect wallets.

Yeah, that’s how I connect my Core to my Sparrow - through setting up the Electrum server.
That was not what I actually meant. I meant, it would have been a good idea for Sparrow to include Knots nodes as its public nodes. That was the point of my feature request.
As far as I understand even the core connection in Sparrow requires the wallet functionality to be enabled in the server so wouldn't consider that recommended approach. Electrum is the way to go
