- Storage location setting: the notebooks can be moved into a folder kept in
sync by Nextcloud, Google Drive, Syncthing etc. (subfolder `ink-notes`);
existing notebooks are copied there if it is still empty, the originals stay.
- Changes from other devices are taken over while everything local is saved:
changed pages are reloaded, new/removed/reordered pages and titles come in
through the manifest. A page file still being synced is retried later
instead of being set aside as damaged.
- Conflict copies made by sync clients become pages of their own.
- `.opened_by.json` marks the device that has a notebook open; opening a
notebook open elsewhere shows a warning.
