Sorry it took so long to get back to you.
As far as I know, the donation option does not unlock anything you do not already have. It only removes the waiting period in accessing HyperDrive Tweaks. If you really like it then donate. I have not heard of the GPS issue before so I can not be of help. As far as the clock, did you try playing around with its location in HyperDrive Tweaks?
Are you sure about the pro keys? I bought the bronze edition and it seems that there are still some settings in the hyperdrive tweaks that are disabled.
I figured out the GPS: The toggle button was in the statusbar, then I rebooted once and it wasn't anymore which is why I freaked. I found out how to choose my buttons in the statusbar so I put the GPS back.
As far as the clock; I've looked through all of the hyperdrive tweaks and paged through all my system settings. I never saw an option to enable or disable the clock, nor did I see an option to change the position. I did changed the clock settings that I saw (like you I thought the OS would magically figure it out if its attention was called to the clock) and it didn't help
