I love that they are constantly improving their platform! The software is very intuitive for all levels of users - even non techies can use this program.
You do have access to great resources when you need help troubleshooting or learning about new features/tools available through the app. There aren't many things i dislike as far as using the system goes; however if there were some improvements in certain areas then maybe we could see more people adopting holisticly into our organization. Integrating my Google calendar has been so much easier than having multiple apps open up at once (like Evernote).
