From the 9.9 beta 1 Release Notes
New Features
- Sermon Builder
- Added a Sermon History tab in the sidebar that allows users to revert to previous versions of the sermon.
- Added Auto-Complete suggestions for things like series, occasion, venue, speaker, etc.
Thanks for adding the Auto-Complete capability - it looks like it is working well (I have just checked series) and will be really useful.
It looks as though it works in Sermon Manager as well - could be worth clarifying that in the release notes when it ships to the stable platform.
