I like that it's easy for me as user of this tool to create my own flow charts and diagrams in order to understand how things work or what could be improved upon without having to spend hours learning other tools such as Visio etc.
It also has some nice features like being able to add different shapes/colors so you can easily differentiate between them too which makes creating more effective flows easier than using simple lines only (which would make your diagram look messy). Sometimes when adding new elements there are errors but not always - sometimes they just don't appear at all! Also if you're looking for something free then go ahead because once you have used it even though its paid version looks expensive compared to others out there it does come down to how much time we want to put in each task before releasing our product. My main issue here was trying to figure out exactly.
