The fact that it's easy to use as well with all major browsers (IE9+). That I can open any zip file without problems in my browser using this plugin! No cons at least so far;-)I have only used JSZip while working remotely from home but if you're willing/able then go ahead-no harm done:-) If there are other features like compression or encryption which would be good too because they could save bandwidth when downloading large amounts of data.- There should also exist an option where we don't need admin rights just double click our jszipped folder containing many zips inside another one etc., instead having multiple downloads each time needed - maybe not feasible yet?
