Hipstamatic 300 (now at version 354) includes a function to allow you to add a Favorite that consists of the gear from a single pak.
To use this function, open Hipstamatic and go into the Hipstamart (the shopping cart icon). From that page, tap on the My Gear link in the bottom right, and then tap on the My Paks link.
Then, scroll down to the pak you wish to use to create a Favorite and tap once on the name of that pak.
On the following screen, you'll see the 'Add Favorite' button as shown below:
Please note: If the pak you open has two or more lens or two or more films, you will see the 'Mine' label rather than the 'Add Favorites' button. The app is not configured to create Favorites automatically for paks with more than just one film and lens in them, as that could potentially lead to many more Favorites being added than you wish. In those cases, just create Favorites manually as you normally would.
