But I am curious, how do you find this more useful than the diff functionality? I've never seen any editor do that, and I can't personally think of many use cases, nor have I seen anyone else ask this before.

I think it would be quite nice. For instance, I would like to see the TextMate line numbers become bold (or highlighted or something similar) whenever a line changes. Their state would then be reset whenever a file is saved. It would be like having a more fine-grained version of the "file changed" icon in the file's tab. That is, the icon lets you easily see whether the file has changed, and the line numbers would show where the file has changed.

As for a use case, sure, you could use the diff feature for finding changes, but that's not the same thing. Diff is not real-time; it requires you to open up a new window every time a change is made. Patrick's idea would be much more convenient for when you're making many small changes to a large file and simply want help tracking the changes you've made. (In a way, it's kind of like the highlighting of the current line. Not truly necessary, just a nice convenience.)
