I am very happy to have the new zip/unzip commands. I would like some basic compression level options (unless they already exist and I missed them). For this message I will consider the current/default compression level to be NORMAL. At minimum I would like to be have a switch with which I can set between two compression levels: STORE and NORMAL. I prefer to be able to set among four levels: STORE, MINIMUM, NORMAL, MAX. Numbers could be used: 0, 1, 2, 3 (2 being NORMAL) Other names for the levels could be something like: STORE, SPEED, NORMAL, SLOW Regardless of the specifics, being able to set compression levels is VERY useful for me.
