Layout Helpers are used in the layout editor to automatically fill in expressions. There is currently no editor for helpers so the XML must be edited directly.
Helper Tags:
Helper: This is the container tag, each helper is wrapped in a Helper tag.
Name: The friendly name of the helper, this is displayed on the layout panel.
Description: A short description of what the helper does. This will also be displayed on the layout panel when a helper is selected.
Help Keyword: The keyword is used to link directly into the help system.
Expression: A valid crash magic expression. %s can be used where Project, Study, and Report need to be inserted by the layout editor.
Providers: Wrapper tag that holds each provider.
Provider: The object type that this helper can be used for.
Categories: Categories are used to group helpers so they can be easily found from the layout panel.
