The most important thing is that it can be used in both desktop as well web applications, which makes this product very useful for our business needs! There are some minor issues sometimes when we use different browsers or computers but they don't seem like big problems considering how good everything else works so far (the UI/UX).
I would say there aren’t any other downsides about my experience thusfar either; however if you have specific questions feel free ask them here because someone will probably know something :) It's one more tool at your disposal now since every developer should learn javascript nowadays anyway ;).
