Manage catalogs
The catalog system is a bit like a visual database system such as Microsoft Access: you create your own ‘record definitions’ that define what data you want for your records, and then you can add these records, and browse through them. All you need to do is to specify what goes in the records: the rest is all handled for you. Power users can create custom templates for their catalogs to display entries in a customized way (this is covered in the tutorials).
You can have as many catalogs as you like, and some premade ones are provided by default.
