Does anyone have any experience or have any resource topics about creating a docked window on the right side of a browser? What I'm trying to do is after a customer is entered onto a transaction a docked window will appear on the right side of the browser with information inside of it.

I've never used it and it doesn't sound quite like what you're looking for, but there is a split pane library (also comes in a chrome extension version) that might help you here.

Thank you! I will check these out.

What might work better is using an Inline HTML field and populate that with the content you want in your docked window. Just add the field at run-time and put it where you want to see it.
