Could you make it possible for Evernote to save clipboard data? A user could copy data on their desktop, and via Evernote, paste the data on their mobile device. The stored clipboard data should be encrypted because sometimes sensitive data like passwords are copied.
Could you make it possible for Evernote to store bookmarks and tabs? Bookmarks would be synced between different web browsers on a desktop and different web browsers on a mobile device. I like using Firefox on my desktop and Opera mini on my smartphone. Xmarks was a good bookmark syncing service, but it has been shut down. Notes and bookmarks are similar. Maybe you could acquire Xmarks and integrate that service into Evernote. Maybe you could call it Evermark.
