Tags are a great way to further organize your transactions. Tags are much more flexible to use than categories as there aren't so many other items associated and dependent on a transaction's tag.

A transaction can have any number of tags, from 0 to as many as possible before it looks wonky in the UI.

What can you do with tags?

You can set the color scheme for any tag from the Tags page.

You can generate a report or charts based on tags from the Analyze page.

You can break down your spending by tag, or filter transactions by tag from the Transactions page.
