Currently Blue Prism doesn't seem too sleek when it comes to navigating the application. It feels "stuttery", and I suspect that this is due to how the graphics of the application is handled behind the scenes. Whether it is being caused by having to talk to BP-server constantly, or running single-threaded I don't know.
My suggestion is simple - Take a page out of the game developers book, and implement a separate GUI that runs on its own thread regardless of what is running in the core of Blue Prism, such that our GUI is responsive at all times.
This is probably not a small task, as it would alter the way the application is built from the core and up. But it would help increase the quality of the product I think vs. your competitors.
