I like how easy it is for me as an administrator (or anyone) to use this product! It's intuitively organized into sections - which makes everything very accessible from any level of user experience or technical expertise.
There isn't much dislike about using iMixS Office WorkFlow at all; however there are some things we would love implemented such as adding additional fields/templates & being able to create custom forms with your own content. The biggest benefit here has been time savings related to data organization within our team members' workflows.
