Hi Dominique,

Thank you for bringing this to the list.

There's just one current version: the one started by Shinnok and
continued by Aleksey.  Yes, it is called Johnny.

What do you mean by that?

I did not mean to emphasize this performance and scalability issue - I
merely answered your question (off-list) on what it was about.  That
said, speaking of a possible hierachical tree view, a difficulty is in
deciding how to reasonably turn the list of password file entries into a
tree.  We could simply use a two-level hierarchy, with the top level
having collapsible entries, say, for each 1000 of the original list's
entries (so they'd be called e.g. 1-1000, 1001-2000, and so on).  Or we
could group/split them e.g. by the first character of the username (then
we'd have the original problem back e.g. if an artificial sample file
has all entries with the same username).  Or we could have separate
sub-trees for fully-cracked/partially-cracked/not-cracked passwords
(just 3 or 2 of them, depending on hash type).  Or we could have
separate sub-trees by hash type (if multiple hash types are present at
once).  Or we could combine several of these approaches (then we'd have
more than two hierarchy levels).  Maybe these should be optional
alternatives to the obvious flat list approach, which I think we should
support either way.
