Client Facing - thumbnail view of design boards

When you are in the client view it would be great if they could have a screen that showed all of their boards like we can see when we click on designs. For some projects where I'm working on the whole house we have 50+ boards and so for them to jump around or find something from earlier on in the project it takes them some time to scroll through the boards. If they could click on one button and see small thumbnails of everything that would be really helpful.
