The QuickLook button looks more like it's meant to search the files in the archive #45
Description
In various different apps, the QuickLook button generally looks like an eye... also in Finder, if you click to customize the toolbar there's a QuickLook button with an eye on it...
Magnifying glass is generally used to search something...
So I suggest to change the symbol for the QuickLook button to make it more consistent with other apps.
BTW... since it now looks like some search button... it could be useful for archives with many small files to have some search field... it doesn't have to search the contents of files, but at least to search the filenames... and maybe to make it consistent with Finder place it where the "..." menu is now and move what's in the "..." menu to the Menu Bar (the Archive Info button can maybe go to the toolbar, but maybe call it "Inspector" and instead of just opening Get Info make it look more like some panel or a window that belongs to the app with additional info about the archive that Get Info doesn't show... like if it has multiple parts or some extended attributes). Since Mac apps have a Menu Bar, they usually don't seem to have a "..." menu, unless it's some multi-platform app like Chrome that places various things there to be consistent with their Windows and Linux versions.
