Supposedly up again now

no, as far as I can see there is no way to configure the Jetbrains plugin to use a local endpoint.

Yes, I get the same vibe, as one has to sign in to their site to use the plugin. Kind of grimy for them to seemingly imply that it is locally run when it isn't.

Why not?

Can someone make a better plugin?

Looks like it could be very useful for frontend design in general; having the right information where the eye would naturally go would be huge for UX I think
