I find that though database and attachments can be synced with built-in sync function or third party softwares, the preference of zotero and addons cannot be synced. This reduce the working efficiency of people who have multiple devices (people may use their workstation, laptop and pad at different occasions).

I use VS code too, and I recommend its settings sync mechanism with a good experience. The settings can be synced by overwriting synced personal modified settings onto the default settings defined in VS code itself and extensions.
