Google Spreadsheets (not Docs) allows me to upload a new version of any spreadsheet file I have edited offline and I want this feature in Buzzword. Practically speaking, it would allow me to more easily integrate my online and offline responsibilities since my sharing and other settings would be maintained. Euphemistically speaking, the paper world would talk to the digital world more easily.

Currently, if I edit a file offline I would have to either copy and paste the new content over the old OR upload the new file, delete the old, and recreate the sharing settings. This is not very efficient and it's easy to forget the last step. It's also annoying and time-consuming to have to reapply the sharing settings each time.

"Upload New Version" would be a very convenient feature that should be relatively easy to implement. The content in the new version of any file would simply replace the old version and the version log would need to be updated to include the change. No one need be any wiser.
