Orbit is now in the renderer process in the Electron app. Sending a message involves signing which is heavy and yanks the UI sometimes, so it'd be better to do that in the main process.
I thought about this and looked into the code and it actually doesn't make sense. Signing a message is not done that often (unless you spam on purpose) in the UI, so it's fine to keep it there.
