You know what I really miss in the file browser?
The ability to unzip files.
It would be one of those benefits that would make me try a third party file browser.
For example... you download a file on your phone, which you want to use right away on the phone. But oh dear... it's zipped. Or compressed with Rar.
And yes, I know there is a small command line based zip tool for in the terminal, but that is just cumbersome IMO.
