I've updated my Weight & Balance spreadsheet for the A36 Bonanza (with Osborne tip tanks). This is the Apple Numbers 3 version and will run on a Mac or iOS device. I've added "standard items", such as spares, bags, aircraft cover, and you can select whether the item is on board, and if so, if it's loaded forward (behind pilots' seats) or aft.
The spreadsheet could easily be converted to use with other aircraft.
Download it here if you'd like to use it.
