Toolchain editor - Feature Request

I propose the next improvements to improve the editor (by order of priority):

• Use the right button of the mouse to show an informative menu with the options available in each case: block selected, line selected, blocks and lines selected, etc. Possible options: delete, copy, cut, info, etc.
• Include 2 new scrollbars (horizontal and vertical) inside of the toolchain map
• Move "Save" and "Close" buttons up and make the editor operate a bit more like an WYSIWYG editor
• Add "Zoom-in" and "Zoom-out" buttons to the new bar on the top, together with the "Save" and "Close" buttons
• Copy/Paste selected blocks by the mouse. Using the mouse right button (previous point) or the keyboard Crtl+c (linux/windows) or Cmd+c (mac).
