Thanks for the reply. As much as I value your opinion, the point I was trying to make is that more testing is needed, I just gave some examples in order not to sound negative but constructive. I know that the current approach to testing is cheap and efficient, but I would advise proper testing sessions, mainly on usability and user experience. Hire 4 testers with different skill levels on Spriter (minimum for a limited budget, testers usually take 50$/hour), and observe how they approach the product. Ask questions, like "Do they get it?", ask them to perform key tasks and watch how they work. I think this will not only reveal bugs, but even usability issues.
Personally I don't have the time to test right now, even though I want to help improve Spriter. I am using Win 10. Regarding Ctrl+D, that's a functionality for copying an object into all frames: https://puu.sh/tb1Y4/fe40ba978f.png Regarding the trial version, there was a video that mentioned that and I was surprised and I didn't download the latest patch thinking that I would lose access. If I find the video I ll link it as an edit.
