• Auto-detect which server configs actually support Steam Workshop before showing adapter controls.
• Allow players/admins to reorder selected Workshop mods in the new picker UI so load order matches game expectations.
• Surface pagination controls in the Workshop picker so users can request additional batches from the new Steam Web API search endpoint.
• Add an admin-facing toggle that makes it clear when the HTML scraper fallback is in use and lets staff force API-only mode if Valve ever objects.
• Add Workshop result preview thumbnails and author links in the picker for easier browsing.
• Add a lightweight admin UI report that flags remaining PHP files still relying on legacy PHP 7 constructs not covered by the automated compatibility pass.
• Add a side-by-side before/after diff preview panel to the config_games top-level XML section editor before section saves.
• Add an integration smoke test that exercises paid checkout, free checkout, and add-to-cart on installs with/without period_start to prevent billing schema drift regressions.
