CataBlog 1.5 was released earlier today and features the new gallery section. With the new gallery section you can create custom collections of library items and save them in galleries. The main function of this feature is to allow people to organize their catalog library items in arbitrary ways that aren't possible with categories alone.
To make a gallery simply open the CataBlog Gallery Admin Panel and use the form on top of the list of galleries to make a new gallery with whatever name you want. Once you have made a gallery go to the CataBlog Library Admin Panel and check the checkboxes next to the items you want to place in the new gallery, then select 'add to gallery' from the bulk actions drop down menu. You should then pick the gallery name from the drop down menu in the modal form and click the 'Add to Gallery' button.
Once you have created a gallery and added some library items to it, you may want to edit the gallery. Simply go to the list of galleries and click edit, once in the edit gallery form you may change the name, give the gallery a description and remove and reorder the catalog library items in the gallery. Make sure to click 'Save Changes' to finalize all your edits before leaving the page.
Here is a little preview of what the gallery editor look like, enjoy
