If your app slows down the user by having to make repetitive tasks because your UX is lacking, then there's a whole lot of no responses to your questions. Not really sure how that's hard to comprehend. Eliminating repetitive tasks is why we invented computers. Using a computer to create a new method of repetitive tasks is not good use of those computers or the user's time.
It's like the first gens of iOS that did not allow for copy&paste. Was that a shallow bit of feedback? No, because it's some of the most basic functionality a user would expect to be there. If iOS and no copy&paste was released in the 1980s, it might have been forgiven. Since it was released in 2007 after anyone using computing had seen/used copy&paste and the competing product did have that functionality, it was a huge slight against it. Was copy&paste the core functionality? Probably not, but it was a huge hindrance.
After getting past the fact this is node based editing, it's pretty much an image editor after that. Again, if anything you try to implement is less than pre-existing software, what's the point. So, when you present an application that is supposed to be paradigm shifting, you better be backing it up. Again, don't want public comments, don't post the software to public forum created solely for public commenting.
