Alphabetic Sorting
There are two options for sorting pigeonholes alphabetically.
1. You can have Pigeonhole maintain the entire group in alphabetic order.
With this option selected, the group is reordered automatically each time you add or delete pigeonholes. Ordering the entire group is also reversible. If you deselect the option, your pigeonholes are returned to their original positions.
2. You can sort a selection of pigeonholes within a group. Select the pigeonholes you want to sort, right click in the selection and click "Sort A to Z".
Selection sorting is not reversible.
