I like how easy it is for users with no programming experience at all to learn our system and create useful widgets.
My team uses this product daily in their jobs but we have not come across any problems yet! It's so simple anyone can use it even without professional training or skillset - great if what we are looking for requires little effort from user side (like customizing layout). If you need an intuitive tool where almost everything can be customized easily by end-users then try out CantataWidgets - they really do solve every problem when dealing with complex widget building process. We needed something very specific in terms of functionality which could only be achieved using advanced customization options available through cantatawwidgets dashboard interface rather than coding them directly into HTML/CSS code.
