Something like this?
This add-on uses the poller idea from How to poll a Google Doc from an add-on to call a server function getRecord(). That function grabs the row of data that is currently selected, and returns it to the showRecord() callback on the client (JavaScript) side, which handles the presentation in the sidebar.
It's not complete - watch for TODO comments. I wonder if this would be worth further developing and publishing?
