Thanks for feedback, much appreciated. Yes I totally agree and multi device sync is a top priority that will be hopefully implemented in the next release.

I am developing this program out of personnel need so it keeps me motivated to keep improving it.

Packaging definitely on my todo list: it will cover all common unix platforms

The program relies on pulling the bookmarks out of the filesystem. I have no idea how feasible it would be on Android given the sandboxed nature of apps.

However, it is possible to manually export from time to time your bookmarks to a folder that is synced with Syncthing for example. Gosuki has a bookmark html auto import feature that watches a folder and imports all bookmarks files when a change is detected. This is how I am personally doing it right now.
