I agree. It's simple for user. Actually, I didn't know there is copy
items in the halo menu. That's too tricky UI...

Thank you for the information. I'll take a look deeper. I thought RTF
just because Sugar's clipboard (right edge of the frame) said "RTF
File" when I copied in Write activity. Maybe RTF is text/richtext?

I didn't quite understand though, You mean that the drag target is
drawn on out of the squeak image? That's attractive.

umm, it seems not to be easy to make for me... I prefer to start
stupidly simple at first. What about to use X halo for cut, and
duplicate halo for copy?

Yes. Let's follow Write's convention as well as possible.
