There is a capability called "Folders" which are user-definable forms in the web-based Admin module and exist in Contacts, Accounts, and Tickets.
Since it doesn't take very long to add this capability to other modules, we plan to add it wherever necessary.
We are also working on a flexibility layer (for release at some point) that will include embedded folders within specific pages. This would allow for custom fields added to existing pages, for example, the account details page without having to see a separate folders tab.
We are always interested in more fields so if you have a list you can provide we'll review them for inclusion.
If you are a developer then new fields can be added in a few steps, but require some maintenance if not submitted and included in the core distribution.
