I suspect that the case insensitivity thing is a Windows oddity;
:Nexplore and :Pexplore work in the same sequence as files are displayed
in my testing under linux (capitalized files display before
non-capitalized files).

Not currently with netrw; however, the selected files should be
highlighted with
exe "2match netrwMarkFile /".s:explore_match."/"
ie. does 2match work with your setup? I know that there was one
complaint that files weren't visually made apparent; that was due to the
gentleman's never having had syntax highlighting enabled (which seems to
also disable :match, :2match, etc).

Well, netrw does support the notion of "hiding" (see :help
netrw-hiding). However, I don't have :Explore's "star" patterns tied
into hiding (they're not tied into the marked-files, either -- that's a
change I've considered making recently).
