What I would love to see is an option to also sync the reading list. And, as I can open a group in a new window by double clicking it in the main view I would also like to have that for groups in the sidebar. Since I checked the option in the preferences and nothing happened when double clicking a group in the sidebar I was like “ok, its a beta” but the, accidentally, I double clicked a group in the main view and voila, a new window opened which I didn’t expect.
That’s planned for a future update of the sync.
In views this depends on Preferences > General, the sidebar of beta 2 will also support this.
