GT Page Blocks Builder 2.5.0
- REST API (pbb/v1): full CRUD for library blocks plus /duplicate and /render endpoints — list filtering, search, pagination, and status counts via headers.
- New library admin panel: card grid with live preview thumbnails (lazy-loaded), search, status filter tabs, duplicate / trash / restore / delete, and copy-shortcode — the classic list table remains at ?view=list.
- Block editor: the Page Block defaults to a rendered live preview (auto-sizing iframe with theme styles) when it has content; toggle Preview/Code from the block toolbar.
- Block editor: Browse library — search the library in a modal and insert a copy of any saved block into the current Page Block.
- Responsive preview: desktop / tablet (768px) / mobile (390px) viewport presets, plus a dark-scheme toggle (data-theme="dark").
- Collapsible live preview pane under the code editor — re-renders as you type (server-rendered when PHP/wpautop is on).
- Copy button for the active code tab.
- Save to library: promote an inline block to a reusable library Page Block (admins) straight from the editor.
