Adding & Removing Groups.
At the base of any Wallet database are groups, folders which enclose multiple entries. They can be used to organize and separate different types of data.
Creating a new group.
To make a new group, click the "+" button under the groups list. Or, go to File>New Group. You can specify the name, icon, and headings used in that group. Headings specify the amount of fields in entries in that group. You can also label each heading. You can have as many as 6 headings, and as little as 1. Usually headings will determine what type of data the group stores!
Removing a group.
If you need to remove a group, just click the "-" button under the groups list, or hit the delete key on your keyboard. By default, you'll be asked if you want to delete this group. You can turn this off in the Preferences.
You can not delete the last group (there must always be one group in a Wallet database).
