[Feature Request] Inline diffs

[nickciaravella]

The current diff view layouts all have the old and new shown in different splits. I'd love to have a layout where there is just the file picker on the left and an inline diff of the code on the right. Very similar to VS Code when you have the "Source Control" explorer on the left and your diff view set to Diff editor setting set to inline.
