Keurig made this superfancy machine with the superfancy milk frother and didn't bother to include storage for the milk frother lid. That's very un-fancy. Bring back the fancy with this lid storage so your milk frother cup so you can store the lid while you're waiting on the cup to dry after washing.  Two versions are available:

1. rev000: lid can be installed in either orientation
2. rev001: lid can be installed in one orientation (it's probably how you'd prefer it anyway) and the bottom is open to ensure the lid dries quickly after rinsing

Keep your fancy stuff dry after washing. Nothing is less fancy than wet stuff.
