Hi Alvin,

You can add or delete filters as frequently as desired.

If you want to delete a filter that has already been used on accounts (or customers or vendors or items or orders, etc), go to the Maintenance menu and choose 'Apply Styles'. There is an option there to 'clear unselected filter styles' when you apply filters and styles from here. This means that any accounts that don't match any selected filters get the 'automatic style' reset.

From this screen, you can choose this option and none of the filters. This allows you to reset all filters and styles, removing all style colour and special fonts.
