Option request: hide pickup count icons in the overlay when completed

[DrYoshiyahu]

It would be great if there was an option to hide items in the pickup count row after they have been completed.

One of the things I love about the tracker is watching the icons disappear after they're complete, but the pickup count icons always stay there, even after completion, which just slightly increases visual clutter, especially when one is nearing completion of all achievements, and the tracker should be almost empty at that point.
