We have added uKeeper->DropBox integration. See Extras or just go directly to http://www.ukeeper.com/dbx/
As soon as you activate this service (disabled by default) all of your drops will be saved as regular htmls with all corresponding images to Dropbox/ukeeper/[date]/[article] in addition to the existing email processing. Click on index.html will show the article in the same way as you see it in your email or evernote client.
Such functionality allows to keep the backup for all of your articles and access them directly (locally) from your browser, Finder and so on. In the future we will provide some simple web-ui to make this access even simpler.
