Configuring Slicer GUI layout and display

General Information

Background: this module is set as Slicer's default startup module unless a user checks the box (in the User greeting panel) to supress this behavior. If the option to show the welcome module at startup is de-selected, Slicer will display the user-specified Home module on startup. The Data Module is selected as Home unless a user explicitly chooses another module.

Module Description

This module is intended as a welcome screen and basic overview of the Slicer software.

Detailed Description

Each panel in the Welcome Module is intended to provide basic information to help new users become acquainted with Slicer. The following informational panels are provided in the module, and populate the GUI from top to bottom. They provide a brief overview of their respective topics and provide links to additional information. Note: we would like to sincerely thank members of the Slicer User Community for helping us to design this information overview.
