Added
- Hide Terminated Friends - automatically hides deleted/terminated accounts from the friends carousel on profile pages (on by default, toggleable in Profile Page settings)
- Games now appear above players in Quick Search results
- "Hide Standout Games" toggle - hide the curated Standout Games section from the home page (works at both API and DOM level)
- New toggles for previously always-on features: Random Server Button, Rejoin Button, Playtime Display, Updates History, Badge Enhancer, Private Servers Toggle (Game Page)
- Sidebar link customizer - add, remove, and reorder Stats/Themes/Sandbox links in the left sidebar (Navigation settings, supports both old and new sidebar)
- Pinnable settings - pin up to 6 boolean toggles from the options page into the popup for quick access
- Pin icon appears on hover next to any toggle in the options page; pinned settings persist locally
- Popup pinned grid: full-width toggle rows that update settings instantly

Fixed
- Playtime data being permanently wiped on logout or account switch - user data is now stored per-account and never deleted automatically
- Active game sessions not being finalized before account switch, causing in-progress playtime to be lost
- Catalog hover preview: single click now navigates to item (was requiring double-click); scroll-zoom no longer hides the preview; right-click panning works reliably
- Catalog hover preview not showing accessory items when user already has 10 accessories equipped - now evicts the last base accessory to make room
