Hide unchanged lines

[notgoing2bauser]

I just read this in the FAQ (http://manual.winmerge.org/Faq.html):

4.6. Can I hide similar lines in a file comparison, so that only different lines are visible?
No, you can't. Many users have requested this feature but we don't have any plans to implement it. We don't believe it would really improve usability.

I came to WinMerge as I forgot to bring my current comparison tool (UltraCompare) to the client's office. I need to review the significance of the 40 different lines in two 2.2 million line files, but there is in fact no way to see these changes together on the screen, instead I must jump around between them? And you can't see how this feature would improve usability? Well, for this user it immediately removes WinMerge from my potential tool list.

I like the "Hide unchanged lines" feature, but what I am missing is an option which does NOT show the lines "x line(s) excluded". In my case it does not tell me anything new as I have markers in my file, actually page numbers, which I have not identical on purpose so I can readily find any diffs on a page.
If this can be done with the line filter I would be happy to use that, but I have not the slightest idea where to start there, this assumes of course that that is even possible with the filter.

Thanks for listening and your consideration.
