Problem

Want to know what's new.

Hard to follow conversations.

Solution

Document Activity Panel

Sorted by Time.

Document Discussions Panel

Grouped by Threads.

Timeline and Grouped by Threads are incompatible.?

We can have both views: Discussions and Activity Views on the Document Panel, but also on the General Feed Panel.

I'm starting to get used to it. As a unified feed I think it's not bad. As the only way of dealing with comments it's pretty hard indeed.

I keep thinking that having a Gmail-style threads in a separate panel would be a nice way to work with discussions.

Grouped by thread like gmail.
Within a thread have a way to display it chronologically (flat) or in hierarchy.
Updated threads move up to the top.
