Interesting idea! I had one big issue with it, and a couple of minor details about the programming.
The big issue is that the description of GO TO WINDOW led me to expect that the sprite would be attached to the window. You can do that with SET [MY ANCHOR] TO. Thereafter if you move the window, the sprite will move with it.
Strictly speaking, we don't make any promises about the order of the clones in the list reported by MY CLONES, so it's better to use the new clone directly in the TELL. (This is why having the reporter version is so much better than just the command!)
And one more, which is that you can save some time by taking advantage of hyperblock features. For example instead of
This part makes the title bar and the window body. Your modified version turns every pixel to that pixel, and it's not how i intended it to do. The code i made is not that complicated but it's optimized enough to make a window.
This update, however, is major. I am going to attempt to add something like it, OS7 will support more apps with windows, but for me to add resizing is something I really don't want to do, seeing as this version is releasing in about 8-9 days.
OS8 (Codename: Clementine) will have many new features I can't say.
I'm already beta-testing window resizing with ColdFusion Architecture, but that won't be for this major version.
If you want window resizing, and that's all you want, go to Frames OS.
If you want games, apps, community features, and more, go to SnipOS 6.
