above/below diff view instead of side-by-side

Firstly, I don't know whether this has a real term or not. So apologies if this is a duplicate.

Meld shows file diffs side by side. But I work with portrait-oriented monitors, a large font size, and often deal with generated files with long lines. I'd like to see changed lines over/under each other, rather than side by side on the screen. Here's an example of what I mean:

It would be nice if Meld could provide a similar layout, but consistent with its current style (ie. red/green highlighting instead of +, -) and with the full context.
