Branching makes it cheap to try things, so a workspace fills up. The Landscaper finds empty conversations and branches you have stopped using, and helps you clear them out.
Open the Landscaper and run it. It looks for conversations you opened and never wrote in, and for branches that have sat untouched for a while, then suggests what can go.
You pick which of the suggested branches to delete, and pinned conversations are left alone.
See it in the app: What's new under Help walks you through each update.
