Add missing from a public profile is one click and sends every missing title, capped at 20,000. Most-played and featured titles go first. The pending list stays on the catalog until each id is sampled, then that row is dropped. The filter menu shows how many remain and when that should finish.
Player Rising, Falling, or Holding, the dashed overlay, and the estimate daily term fit each day's 24h peak, not the current hourly sample. Overnight troughs do not flatten a climbing evening peak.
Privacy and Terms say the same: queuing missing ids is every missing title in one request, capped at 20,000 ids, three times per hour per address.
On a phone, game-page range and estimate horizon are dropdowns so they are not cut off. Estimates stands out as its own control. The PNG save is an icon and stays readable at a narrow width.
The filter panel is quieter: short profile id, icon refresh, and one line for how many owned titles are on this catalog. Steam Deck chips are shorter.
Add missing titles from a public profile now reaches the catalog. Website only, short-lived cookie, not a published API. Up to 40 ids at a time, three times per hour. They appear after Steam pages are fetched.
Library import is a website feature, not a published API. It needs the short-lived site cookie; a script without it is refused. After a successful paste, Refresh reloads from that public profile. Ids stay on this device. The steamid is not stored.
Privacy, Disclaimer, and the FAQ say the same: six imports per hour per address, and that overlay is not listed for callers of the public API.
