I posted this on the monthly call chat log - but thought I'd add it here too...
Something like this would be life changing for my users....
If they could start typing a vendor names, customer names or material names in a field and it would autocomplete like google suggestion while they type (as opposed to having to search for vendor numbers using wildcards, or cities, etc)
This would blow all of my users' minds.
I use similar UI elements with jquery or AJAX on some of my websites
