In the below example we can see how making a couple of changes is hard to track as the entire paragraph is shown twice  Conversely, in the below example we can see how much more efficiently changes are shown using word-diff  ### Proposal Since git natively offers a `--word-diff` for these cases, users should have a mechanism to toggle this mode. Add an additional button `Word-dff` to the Inline/Side-by-side split button  ### Additional points / References / Links It might be worthwhile considering to word-diff certain file extensions, such as `.md`, `.txt` etc. by default. Classic Line-by-line code diff most likely is also the root cause behind this issue: https://gitlab.com/gitlab-org/gitlab/-/issues/16713 <details> <summary>Previous description</summary> Word diff highlighting makes reading diffs much easier, and these are supported in GitLab, but we can improve support. | **Merge request** | **Commit** | |---|---| |  |  | ### Proposal - merge request suggestions - prose (rendered markdown) </details>
