By collections I meant morphs in a book/playfield/holder etc. Here is an
example:
I drag a curve morph onto a book. I can use redbutton to pull it out and it
works as expected. But bluebutton halos the whole book. Since most books have
lots of blank area to pick, this behavior is counter-intuitive. The morph
which responds to red should also be the morph which responds to blue. Morphs
placed in playfield work as expected. This is in 3.10 and also on 3.9.
BTW, I overheard my kids distinguish embed and drop ops thus:
'embed' is like pasting pictures onto a sheet. It sticks and becomes one with
the sheet. 'drop' is like placing blocks on a tray. When you move the tray,
the blocks also move with it, but they are not one.
How's that for 'advanced' :-).
