I worked with Gokay on a new document compare view for COOL Writer. Part of that feature is to be able to highlight the matching part of an insert or delete on both sides of the view. So if you have a deletion in your document, then we color that red on the left hand side and gray on the right hand side; we color inserts gray/green similarly, in a side-by-side view:
Now if you hover over a tracked change with your mouse, now you get a highlight for that piece of text on both sides, to match the same parts of the old and new version better. A deletion looks like this:
This also works for inserts:
