UltraConvert 1.3.0 — Native UX and Finder format shortcuts

UltraConvert 1.3.0 improves the native conversion workflow and Finder context menus.

• Finder Services format shortcuts for PNG, JPEG, WebP, MP3, Opus and MP4. Select files → right-click → Services → Convert to … with UltraConvert. Review the selected format and click Convert.
• File-row right-click actions: reveal original/result, copy names/errors and remove rows. Retry Failed loads only failures for recognition and review.
• Source → target previews, clear error labels, compact status/action layout and accurate skipped-only completion.
• Cached queue rows and coalesced progress updates. Five alternating samples reduced synthetic 1,000-row recognition preparation from 1.62s to 0.12s; this does not measure engine speed or drawing.
• Both original Finder Quick Actions retained and verified from cold launch. Convert Here still saves ordinary files beside their originals; reports remain separate.

Verification: 134 representative backend checks, expanded native assertions, installed mixed-batch and Finder interaction crawl, Ruff/Bandit/dependency audit. See UX rubric and limits for the developer 9.0/10 assessment; this is not an independent usability/security rating. Both macOS and static CI jobs passed for the exact released commit.

Installation: download the macos-arm64 ZIP, extract its complete UltraConvert folder, open Terminal there and run python3 install.py. The DMG contains the same installer folder. Homebrew engines and a separate Python runtime are required. Public builds are ad-hoc signed with Hardened Runtime and are not Apple notarized. Intel and older macOS are unverified source-build paths.
