Diff View for "diff"ing two files

My view has a split screen with 2 instances of TextEditor. I can highlight the diffs in the text editor the way I want based on the diff engine's output. The question I have is related to line numbers and scrollbars.

1. I want to be able to include blank lines without incrementing the line number (is this possible?)

2. I want to be able to sync scrolling - I think this is achievable by binding the scollbars?

3. I want to highlight the diff's on the scroll bar or on a region next to the scroll bar. Is this possible?

Thanks for this awesome text editor !
