What is new in Swivel 1.0.0

The first public release.

- **The wheel.** While dragging files, tap ⇧ for Convert, ⌘ for Tools or ⌃ for Actions.
 Scroll or tap another key to switch rings. The keys can be changed in Settings.
- **Convert** images (JPEG, PNG, HEIC, AVIF, TIFF, GIF, PDF and more), video (MP4, MOV,
 ProRes, GIF), audio (M4A, WAV, AIFF, FLAC, AAC, CAF), documents (text, RTF, HTML, Word,
 OpenDocument, PDF) and archives (ZIP, TAR.GZ, TAR.XZ, 7Z, Apple Archive).
- **Tools:** resize, crop (presets and an editor), rotate and flip, fit to a size (under 1, 5,
 8 or 25 MB), compress (images, video, audio and PDFs), remove the background (macOS 14 or
 later), remove metadata (photos, video and PDFs), recognize text, merge and split PDFs, make
 and extract archives. Compress and Fit to Size never save a copy that isn't smaller.
- **Actions:** share (AirDrop, Mail, Messages, Notes, Photos and more), metadata, a floating
 shelf, copy, move, copy the path, open in Terminal.
- A welcome window with a practice wheel on first launch.
- The `swivel` command line, inside the app and installed by Homebrew.
- **Shortcuts.** A **Convert File** action for the Shortcuts app: files and a conversion in,
 the results out, saved next to the originals. Builds folder automations and Quick Actions
 without the wheel. **Convert to JPEG**, **Compress** and **Convert to PDF** come ready-made,
 in Spotlight too.
