You just can't win can you?

You suppose that I'd use BASH for this? Hmmmm...
Python has built in directory listing and sorting
functions. Imagine spending 3 secs on /usr/lib/ then 2
seconds on /dev then ... and so on. I just don't think
that the time penality is worth either system (neither
of which you are happy with either).

I am not ready to write the confirm dialogs in. I am
working on the mime-type editor.

Do I look like this is a _real_ concern of mine? If I
really cared, I'd put an option in the preferences
menu.

Single click expansion + "peeking". Peeking is
impossible. You either have to read the directory
until you find a directory (in which case you minus
well just list the thing) or you wait. Those are the
two choices.
