DingoSearch 0.3.1

• Rebuilt the panel engine selector as a custom dropdown showing icon, name and URL placeholder; fixes the Firefox toolbar panel not resizing for the floating menu
• Better empty states: the "More" panel shows a hint when there are no targets, and the context-menu "More…" entry becomes a disabled hint when no engines or groups are configured
• The options page now warns in the selection-bubble scenario if site access permission was revoked, with steps to re-enable it
• Removed 4 unused demo videos from the help page (replaced by frontend animations); extension package shrunk from ~1.06 MB to ~0.43 MB

What's new in 0.3.0

• Address bar "@direct" search — type ds @alias keyword in the URL bar to search instantly with any specific engine or group. Aliases are configurable in Settings and are auto-generated when left empty.
• Sidebar panel — the search panel can now live in the Firefox sidebar (choose "toolbar popup" or "sidebar" per scenario in Settings).
• Multi-select search — the panel's "More" section lets you combine several engines and groups into one ad-hoc search.
• New Help page with interactive looping demos (address bar / panel / selection bubble), setup guide and FAQ.
• Search history upgrades: keeps up to 20 entries (was 10), click an entry to refill the input, and remove single entries with ×.
• Tab key now cycles through the panel's dropdown options.
• Drag-and-drop reordering for groups.
• 6 new UI languages: German, French, Spanish, Brazilian Portuguese, Russian and Japanese (9 languages in total).
• Fixes: the text-selection bubble could occasionally not appear on some pages; context-menu "More" query prefill; sidebar focus/carry-over issues.

Note for users upgrading from 0.2.1: this release requires no new or re-approved permissions — the permission set is identical to 0.2.1, so the update is seamless.
