Funny to see how the 'You are leaving Evernote' message becomes something of a prophecy. Evernote has continuously decreased in both speed and functionality over the last couple of years. Today I was bothered by this annoying 'feature' once again and wanted to check for a setting to disable it. Instead I discovered this thread, going on for over a year now without even an official response. Really shows how detached from its aim and users Evernote has become.
Moving to Simplenote for my main note program, Evernote will remain a backup for the graphic notes for a while but if somebody has a better alternative please let me know.
