We can have fully synchronised notebooks and local notebooks.... but what about something in between? I.e. 'Sync on request'. What do I mean by that? A notebook that will sync to the cloud (and thus be available everywhere) - but will only sync to a particular device when explicitly requested to do so. When a device is 'unsyncced' the notebook remains in the cloud, but all traces of the notebook are removed on that device. Each installation would have an option to 'get "sync on request" notebooks by default' - and the default would be 'off'. Application: When using evernote on a work machine, I may not want to have private notebooks synchronised to it, however, I would want them to synchronise to all my other devices.
