Zola's UI is clean, quick, and easy to use. Their support team is incredibly professional, helpful, and responsive. As a user, it covers almost my full range of needs without being invasive.
My dislikes, minus one, are mostly nit-picks.
1. The color scheme might turn some away.
2. It's also still adding features, so there are a few parts that feel somewhat less polished than others.
3. As a matter of personal preference, I'm not a fan of the fact that multiple tabs of Zola must be open to make use of all of its features.
4. I'd like to see integration with Google Drive added. I can sync with Google Calendar and Gmail, so this feature's absence is more noticeable.
As with any software, do your best to know what you're looking to accomplish, but don't be afraid to try new things. And if you're not sure, just ask; there were a few times where I thought Zola was missing a feature only to find out through support that I was overlooking something very simple.
Zola has been a great asset in our transition to a paperless office, and they make it easy to use the platform equally well at the office, on a mobile device, or in the courtroom.
