"Compared to other frameworks I have used, Sintel forms is so intuitive and a pleasure to work with. Pros: -User interface is slick and modern looking -Having a WYSIWYG editor for form creation is powerful. -The workflow alone actually won me over, It’s so intuitive. -Having an separate actions menu for the workflow makes so much sense and hugely improves our product. -To be able to save, no matter what state you are in is also invaluable. -The ability to use JavaScript (even SP API calls) is a real winner! There are some disappointments and suggestions however, -There is no ability to do modal forms with child lists, something which I would have expected -I would have liked to further customize the layout particularly the color of the fields (as an example when they are read only) -The Logic section can get very busy quickly when you have a lot of rules. would be useful to have some way to manage this perhaps using sections or collapse option."
