Custom Category & Account Sorting

Add the ability to manually rearrange the order of categories and accounts instead of only sorting them alphabetically or by default order.

This would allow users to organize their FreeBudget setup in the way that makes the most sense to them. For example, users could place their most-used categories or accounts at the top, group related accounts together, organize categories around their personal budgeting workflow, or control how items appear in the Dashboard, Reports, and Budget tabs.
