Hello.
Another things I was thinking about is the "copy of directories with the same name" via the GUI. I noticed in other OSes, when you copy a directory into a place that already has a directory with the same name, it asks you to "combine" the content of the directory (or sometimes it even does ask you, it just combine it). While OS/2 asks you if you want to only replace the directory with the new one without any combine option.
Regards
