The Keeper.sh dashboard has been rebuilt around connections: which calendar copies into which. Each connection shows where events come from, where they land and what is copied, so you can check that your work calendar blocks time on your personal one at a glance.
Each calendar has its own page for the settings that apply to it, instead of every option sitting in one long form.
Sync status is shown, not inferred. You can see when a calendar was last read, whether the last run had a problem, and what that problem was.
What each calendar can do explains the settings on a calendar's page.
