Phones and iPads now clearly show that moving installed plugin files is not supported. Applying sync choices no longer opens an unusable cleanup prompt. Existing local backups remain viewable, without move or restore controls on mobile.
On computers, the manual file operation lives under Advanced: local plugin files and is labelled Move out of the plugin folder and keep a backup. This moves files into a recoverable local backup; it does not permanently delete them or free storage.
The settings page also lists recognizable plugins that are excluded in this device's actual Sync settings but are still installed. Unapplied matrix choices are not counted. English and Chinese documentation explain these boundaries.
Validation: 198 local tests passed with no skips, including the reviewed desktop/mobile native fixtures; 75 UI cases passed again after the final wording update. GitHub CI passed 147 cases with 51 expected native-fixture skips. Desktop 1.13.7 installation and settings loading were checked. Existing Sync compatibility profiles and desktop file-operation checks are unchanged. Real phone/iPad transfers, restart persistence, and cross-device deletion remain unverified.
Install the three runtime files (main.js, manifest.json, styles.css) or use the ZIP. A paid Obsidian Sync subscription is required. Obsidian 1.13.7 and on-device compatibility checks remain required; mobile Sync writes still require the existing experimental opt-in on each device.
