There's no Tags Manager (I've added this suggestion to the future features) but you can use Keywords and Tag Words to mark Bookmark records, like so:
1. Open the extra details of a Bookmark record.
2. Enter some tag words in the Reference and/or the Keywords edit fields.
When you're ready to search, use the Full Search.
- Click the Tools icon.
- Select [Search]
- Enter something to search for.
- Press Begin.
Full Search does require your database to be indexed.

Other options for listing specific records can be the use of the very powerful Reports section.

I hope this helps you further in your data storage retrieval methods.
