Autounzip
Unpack as if on a mac
Don't search for unpacked files, they open automatically for you.
No more accidental 'unpack here' which leaves hundreds of files in your current directory.
If you want, autounzip trashes or deletes archives after unpacking for you.

More Features
We use the regular 7zip GUI you know, including dialogs for overwriting files.
Schroedingers archive is the one where you cannot know if the contents are wrapped in another folder. You want no nested single folders, but also no clutter. Luckily autounzip takes care of this and removes nested folders if there is a single one of them.
