I think the branching feature is very interesting and I can see it being of great use to my team as we are moving from Adobe XD to Figma. However, I would love to see a search functionality when browsing the branches in See all branches. I can see a potential issue in the future when looking for a specific branch made months ago.
My idea is to use a branch for each JIRA ticket and name it accordingly. A search functionality would greatly help with the trackability of each design change.
