One small feature I found quite cool in 2010 was on the Links list. The order of links in a links list is generally just the order you add them in. You can create views to sort and filter the items but if you want to just swap a few items around in no particular order you can click the list or list web part, select the Items tab and then click Change Item Order.
Its much like reordering columns in a list view. Choose you order and away you go.
