This PR adjusts the "View More" button in the sidebar to expose threads in batches of 5. Once you've expanded the whole available set, a button to collapse the list back to the default number appears at the bottom. Similarly, as soon as you expand the list even once, a button in the group header shows up that does the same thing. No release notes because this is still under feature flag. Release Notes: - N/A
