For example, I'm incredibly confused about how you're supposedly to measure liquid laundry detergent with the cap. At least the kind that I have sits on it's side, so if you measure it with the cap it just leaks everywhere and makes a mess.
After pouring the detergent into the appropriate receptacle, toss the cap in with your laundry to be washed like everything else. No mess.
It's possible. Just make a LinuxISO (Year) folder in your movies directory and it'll pick up the movie file within, regardless of name.

Naming only matters within folders if you have multiple versions.
