• 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.
• Add a storefront visual-regression check at 375px and 430px breakpoints covering login, order, and cart pages to prevent mobile overflow regressions.
• Complete a full pass over all modules/billing/docs/* game guides to standardize OS/Workshop/RCON capability statements against current XML-backed server support.
• Add an automated billing provisioning integration test fixture that verifies arrange_ports exact/fallback allocation, duplicate-port protection, and home_id linkage after paid/free checkout.
