**Shares** mode lets you assign a proportional weight to each participant instead of a fixed amount. For example, if Alice gets 2 shares and Bob gets 1 share on a $90 bill, Alice owes $60 and Bob owes $30. This is useful when some people consumed more than others but you don't want to calculate exact amounts.
