Back and Forward Button (like on a web browser)

Sometimes I go back and forth between projects or clients or invoices, etc...quite a bit and it would be nice to hit a back button and just go right to where it was I came from. (E.G., looking at a specific project for client A, then looking at an invoice for client b, then going right back to the same screen/data I just came from for client A.

This can also apply within the same client - I'm looking at a project, then the time, then the project, then the invoice, then back to the project.

I think it would make things a lot easier.

I used this feature all the time when we were on practice CS.

Thanks,

Jim
