So I work over a home PC, work PC, and a laptop. I'm already paying for limitless Google Drive, so want to use that. It kind of works, but is not a simple option - you have to set certain directories to sync, and not others (otherwise: corruption). I'm guessing box is similar?

Hmmm. No, I have none of those issues. I sync via WebDAV, automatic sync & full-text content selected. My three computers all have different library paths.

Having never set it up with Google Drive, I'm not sure of anything else that could help your situation. In that sense your original point is quite valid then - this must be a quirk that still needs ironing out.

Looking at it, yes Box works that way, but G Drive does not without some kind of third party integration, and even then for limited storage: https://www.zotero.org/support/kb/webdav_services

My system does seem to work pretty well, I just prefer it when things are very much plug & play. It stops you screwing anythign up, and makes it easy for non power-users to get things done.
