PASS

The interface has been redesigned to make the procedures easier to find, the user input easier to complete, and the output easier to navigate.

PASS Home
The PASS home window now offers easier options for finding the procedures by allowing for quick category views and procedure searches in addition to the menus. A list of favorite and recently run procedures can easily be accessed from the toolbar or menu. A search bar has been added to quick find procedures corresponding to a particular topic. Various procedure categories can be viewed at the click of a node on a category tree. The procedure lists can be viewed in any of three sizes.

Procedure Windows
The flow of the input options is now top to bottom with sensible option groupings. The graphics system has been separated from the primary input, resulting in fewer tabs and more straightforward parameter input. Procedure templates (sets of saved options) can be saved to or opened from any folder location. Currently loaded, favorite, or recently run procedures are easily accessed from the toolbar.

Output
The output now has a navigation tree that allows the user to quickly jump to any portion of the output. A separate output gallery is provided for saving runs of a procedure or various procedures during the course of a session. Graphs can be viewed in a separate window and then saved individually in a variety of formats.
