Something like this has been requested before, and unfortunately ends
up being a lot of work. I did something on this a while ago, but
couldn't get it to work when going from two- to three-way comparisons.

While people are free to look at this, our tree model code is old - it
was all designed before features like GtkTreeModelFilter existed!
Again, while a lot of work, figuring out how to rewrite the current
model to operate with more modern GTK features would be a better
long-term solution.

I'm not sure what you're asking for here... do you just mean that when
showing modified files in folder comparisons, we should only show
files as modified if they're different between neighbouring panes?
That sounds sensible, but I'd have to try it and see.

We don't have this feature, other than by copy-and-paste. I'm not sure
that it's sufficiently widely useful to warrant actually adding UI for
though, since three-way comparisons usually involve moving changes
into the central pane.
