We need you

The icon for the browser extension, and the styling of the bill citation pop-up menu and the drop-down menu have been improved, but the Law Library continues to need your feedback on this project. Staff would like to know whether this makes accessing primary source legislative data more convenient for you, and which features you would like to see added to the extension in the future. They also need feedback on bugs you encounter. Please be as specific as possible with your bug reports so they can be replicated. Please provide feedback to or post issues to the repo.
