Describe the enhancement and the motivation for it.
Using a small screen or a monitor in portrait mode makes viewing changes side by side quite painful. The unified diff format is more space efficient horizontally and the changes are fed to review board in this format already. I would like to see the option of viewing a change in unified format with a configurable amount of context. Note that I am not asking for stacking old on top of new for a top to bottom view of the change, rather I would like to see diff -u output.
What operating system are you using? What browser?
Linux/Firefox
