ZIP-Addon - confusing dialogue

[Peter2]

IMHO the dialogue which appears after pressing "Filter - ZIP Pack" is confusing:

a) Its title is "Save as (Ctrl+Shift+S) ...).
Why "saving"? I want to pack. And the shortcut is used for the "real save as" which shows another dialogue (without the word save as)

b) It displays a field for "File type"
... which is empty, has no default and no entries in the pulldown menu. Is it necessary to enter a file typ? Which? What will happen if I enter "rar"?

Maybe you can modify this cosmetics ...
