Resolution: Won't Do
Affects Version/s: HR-1.0
Fix Version/s: HR-1.0
1. Rename "Summary" to "Contact"
2. Sort all tabs alphabetically (except as otherwise stated) – e.g. "...Career, Groups, Identification, ...")
3. Move "Change Log" to the end
4. Move "Job" tab to the beginning
5. Make "Job" tab default
You might be able to do this by modifying the array in hook_tabs (in which case this will be pretty quick) – either physically resorting the array or adding tabs. If it does need patching, and if the solution doesn't seem "obvious", then investigate and put your findings/ideas on the ticket.
If we do need patching or changes to the hook system, then we may want to do work with the newer/more-generic hook_tabset instead of the older hook_tabs. (Note: hook_tabset doesn't currently work with the contact page.)
