1) not a bad idea, but the idea was to be able to quickly extract to the current folder.
2) do you mean you want to be able to name the folder it is extracted to?
3) i can't realltly create a progress bar as i qm using external apps (7zip, unrar) to do the extracting. Best i can do is show a marquee progress bar (scroll across).
4) I'll look into adding the password support.
