I admit that you want to do more with your list. Just inserting, looking up, or deleting records is not enough. Or is it any fun to sort on one field at a time on a long list, and go down the list to look for what you want. It is tiresome, and is prone to errors.
But Google Spreadsheets in the present state(as of this writing) doesn’t enable you to sort on multiple fields to narrow down to what you want quickly enough. Or better still, it doesn’t filter the list, based on your criteria, to show only those records that you are currently interested.
Don’t despair. There is a way around.
