What changed
The Research page (heading "Research", subheading "Sources the marketing brain uses across your Plan, Advisor, content, and briefings.") now separates sources into modes ("All sources", "My Content", and "Market Sources"), with separate lists per mode. Source states include "Ready" and "Context ready", so you can see exactly when a source's extraction has landed and it's usable by the Plan, the Advisor, content, and briefings. Add via "Add sources" or drag and drop anywhere on the page.
