Priority Queue - Ability To Delete Row / Entry?

I'm trying to get one more feature added to this priority queue tool that a forum member created. Essentially, this attached spreadsheet is a dynamic task/priority list that will change on the fly. See the original thread here: [URL]

The only missing feature is the ability to delete an entry and have all other entries below it change up a rank.

The attached spreadsheet is the almost completed solution

Example:

Original
-----------
Item D - 1
Item B - 2
Item E - 3
Item A - 4
Item C - 5

Remove item B
-----------
Item D - 1
Item E - 2
Item A - 3
Item C - 4
