Yes, it's great, thanks for setting it up. It also works on plebchan btw, they can just paste this line in plebbitOptions, click save, then refresh the page to start the connection.
It would be easier by simply pasting your rpc url `wss://plebbit.works` in the "node rpc" field under preferences > plebbit options. But this is bugged at the moment because of an API schema change, it will be fixed in the next version.
