Feature request: Setting line-spacing / line-height #849

I use guake on a daily basis, and my entire development ecosystem is built around it. Love the terminal, but it would be great to able to set the line height for the terminal. I use VIM as my text editor, and the linespacing can be set in the GUI version, but not the cli and it positively looks much better.

I feel it makes a huge difference in reading (especially code), and would love to see the feature here.
