The top 5 list is a dashboard widget which allows you to select up to 5 nominal accounts to report on.

You can customise the dashboard to show the Top 5 list widget. 

Click on the Manage account codes link within the widget and you will be redirected to the chart of accounts on the Settings > Accounting > Account codes menu.

You can select a nominal account as a favourite to appear on the Top 5 list by clicking on the star icon.

Back on the Dashboard > Overview menu, the Top 5 list widget will display a table showing the balance of the past 5 months for each nominal account that you have added as a favourite. 

You can also view a graph of each account by selecting it in the drop-down box.

If you click on any of the balance amounts, you will be redirected to a transaction report showing the transactions that make up this balance.
