URLs have been extended a good bit in Logos. It would be convenient to further extend them in more areas as a way to launch Logos (desktop, web) directly to Home Page, Blank Layout, Custom Layout, Builtin/Quick Layout with or without reference. The COM interface can be used to open custom layouts, but not builtin layouts. Using URLs would be a really nice (and possibly cheap?) way to allow users to setup links or small tools to open Logos in multiple useful ways.
