This thread is becoming a mess, but anyway. Here is another thing from your "wishlist".
When you drag a pattern and hold CTRL (to copy) it will now show a "link" icon to tell you that you really creating an "instance" of the pattern.
If you hold CTRL and SHIFT while dragging, the icon turns into a "copy" icon, to tell you that its gonna duplicate the content. I think its pretty user-friendly.
We still cant move to other channels, but baby steps...
