What is missing in this picture are changes, which are small enough to
take out entire line, like typos, spaces, punctuation and so on.

IMHO using 256 color terminal emulator is not fancy thing in 2016.
Maybe James suggestion wasn't so pointless? In 256 color capable
terminal, vim diff might can look more or less pleasant depending on


Another idea would be to use vim itself as the interface, and provide a
vim plugin (which could be written in python) for review activities.
Although it may be unsuitable for other editor users.
