Okay, that's disappointing, but I understand. I was hoping there was a function I could enable that would simply display the glossary in the topic panel when selected. We used to provide glossaries in dedicated topics when we were publishing CHM output in RoboHelp 3. I'll evaluate whether we want to return to that format in this one instance.
I do really like the TopNavigation skin, so I logged feature requests to add INDEX and GLOSSARY functions/options to it, which could be displays in the topic pane/panel when selected:
Feature request to add optional GLOSSARY function to TopNavigation: https://tracker.adobe.com/#/view/RH-9780
Feature request to add optional INDEX function to TopNavigation: https://tracker.adobe.com/#/view/RH-9781
Please vote if you agree!
Thanks everyone for the input!
