 - I think the way sublime text and we display line highlights is confusing with multiple cursors (line highlight can be confused with selection)
 - ctrl + delete maybe should stop on new line but it keeps on going, sublime is much more careful with deleting

 - alt right click what to do ? (toggle console?)
 - experiment with using multiple cursors to select command and it's input
 - should be able click on title bar of windows which disappear on losing focus
