I think it would be nice for large picker lists to show a view that contains the item when the list is opened. Right now the behavior seems to always put me at the beginning of the list. It might be reasonable to allow configuring this between SELECTED, BEGINNING, END (default to SELECTED imo).

Closing this ticket as completed - we still have a ticket open for PartitionedTable (#371), but the core functionality is done.
