We’ve improved the agenda experience to avoid “jumping” when moving between items. Agenda points now stay expanded, making it easier to keep track of the discussion. We’ve also added a hover effect (inspired by Outlook) and a grey highlight for the active item.

Also, the 'rich text' option is now easier available, and the default, when creating new sections.
A click on the 'Agenda' button will give you nice compact view of the agenda.
