It's easy to use with all of our clients having their own unique requirements for what they need from us as an agency - we are able to support them in this way! I dislike how it can be difficult at times when you're trying to find something within the system but there isn't anything wrong specifically about spindledocs themselves; however, some things might just take longer than others if searching through documents or finding information which has been uploaded by another user/client etc.
There aren’t any real downsides other then maybe being more efficient with uploading files rather quickly once they've been created?
