 -   LiveSync mode drains more batteries in mobile devices. Periodic sync with some automatic sync is recommended.
 -   Mobile Obsidian can not connect to non-secure (HTTP) or locally-signed servers, even if the root certificate is installed on the device.
 -   There are no 'exclude_folders' like configurations.

 -   Also, with `redflag2.md` placed, we can automatically rebuild both the local and the remote databases during the boot-up sequence. With `redflag3.md`, we can discard only the local database and fetch from the remote again.
 -   Q: The database is growing, how can I shrink it down?
     A: each of the docs is saved with their past 100 revisions for detecting and resolving conflicts. Picturing that one device has been offline for a while, and comes online again. The device has to compare its notes with the remotely saved ones. If there exists a historic revision in which the note used to be identical, it could be updated safely (like git fast-forward). Even if that is not in revision histories, we only have to check the differences after the revision that both devices commonly have. This is like git's conflict-resolving method. So, We have to make the database again like an enlarged git repo if you want to solve the root of the problem.
