Since enough people have requested that feature we have decided to implemented it for the Q1 release without adding a PITS item for that (since no voting is needed).
With the Q1 release you will be able to rearrange the properties in the visual designer. Furthermore some more properties compartment will be introduced so that different types of properties are easily distinguishable (navigational and implemented properties will be put in their own compartments).
Please do let me know if that seems good to you.
