I really like that it works offline as well so you don't have access to your computer while in set/location etc. It's easy for my partners who are writers / directors to use without having an internet connection when they're shooting something but still be able to see what someone else is writing at the same time (if we need them too). There was one instance where i had used maveny during filming with no wifi & just about every other person using their laptop around me were working online - this caused issues because all of sudden there would come up loads of pop-ups saying 'you've got mail' which made us very annoyed! You can also work off line once its been installed onto our computers though. We could write notes and send each others drafts through email instead of uploading files via dropbox etc.
