One of the best parts about Float is how visual it is. You're able to see your cashflow at a glance rather than having to constantly interpret numerical data. There's a feature in Float that does this really well, but is often overlooked: budget bars. 

Simply click on the header of a month and they'll appear.

Within a historic month there will be 2 shades showing what was paid and the remaining budget. 

In a month which is not yet finished you may see 3 shades, what has been paid, what is still due (open invoices/bills) and any remaining budget. If the budget has been fully used, or there is no a budget entered, there would be 2 shades, one for paid and one for due.
