Deduplication search and removal
When you manually enter a new contact Relenta should search the database and find any duplicates. And/or a function to search the whole database to remove duplicates

I can't believe this hasn't been implemented. System wide deduplication is difficult but stopping it in process would be a great help.
Go for the easy fix at least.
And in terms of system wide deduplication, a simple report screen with all the potential duplicates along with some buttons for US to deal with the issue by hand would give 80% of the help for 20% of the work.
