Notes

You can decrease the time it takes for a full-text search by including a full-text search stop list in your project. Any words in the stop list are omitted from the search. These are usually commonly occurring words, such as "the" or "and" that a user is unlikely to search for.
After you add a new tab, you may want to adjust the window size and position of the Help Viewer to account for the new space the tab uses in the Navigation pane.
