Sublime text 2 and Atom currently have the ability to copy content from multiple lines. However Atom is missing multi-line paste.
This video shows the feature I miss from Sublime Text 2
When you copy content from multiple lines and you paste that content one of two things will happen. If you have the same number of cursors when pasting as you did when copying Sublime Text 2 will paste the content from the matching line copies onto the matching line. As opposed to pasting all content onto each line.
I would love to see this functionality in Atom. I use it every day.
