Interesting!
These properties can be accessed from another programs?
Possible useful uses?
Thanks for sharing

Yes, properties of a window can be read by other apps. Not sure if they can be changed by other apps (haven't tried it).

You have right, this code can be usefull, i love codes who can be read property, often hidden of something
And it works here, thanks for sharing
