Looks like you’ve already added the Ctrl+Shift+D duplicate line functionality? I swear it wasn’t there before and I just instinctively used it and it worked! Thanks for taking the suggestion on board so fast.
If I can push my luck: Can we get Ctrl+UpArrow/DownArrow to swap the current line with the one above/below?
Here’s a quick screen capture of me pressing Ctrl+UpArrow in Atom to show what I mean: https://i.imgur.com/dX9OlKY.mp4
Edit: Another super-handy feature would be if I could toggle line-wrapping on and off. At the moment I’m writing some markdown files, and it’d be great to be able to read each paragraph without horisontally scrolling back and forth.
