The ability to create complex workflows with multiple branches in them without having too many tabs open at once or being overwhelmed by information flow while running through it. Sometimes I have issues finding my workflow when using fluid's user interface as some of its features are not very intuitive for new users coming from other systems like SAP BW/4Hana etc. Also sometimes you need to refresh your screen after clicking something else so often that this becomes annoying rather than just refreshing what was clicked before. It helps me manage all our processes across different departments within our organization better which has helped us improve quality control over time. We use it internally but also export flows to customers who can then run their own instances easily if needed.
