Consider a mobile app feature that lets you easily add a camera image to an in-progress note while you are working on your desktop or web client.
Here's how it would work:
I'm sitting in a meeting taking notes on my Mac.
Suddenly I decide to draw a diagram on my napkin, or need to capture the white board, or a document that my colleague hands out. I don't want it as a separate note, but right in with the work I'm currently doing.
I whip out my phone and use the new "add to note in progress" widget to snap a picture with my camera.
On my Mac (or browser) a notification pops up in my current note window, and says "it looks like you just captured an image. Would you like to add it to this note?"
I click YES and choose where in the note I want the image to appear.
