Created attachment 318147 What green progress bar looks like
On applying transformation tools such as Cage Transform Tool the green progress bar instantly shown at the center of the window. When using these tools on small images processing time often turns out to be less than a second. In which case animated progress bar makes very little sense for me. It's just flickering disturbing the user from the task at hand. Maybe it will be better to delay showing the progress bar by a couple of seconds
