With Google Android you can copy-paste a Google Play app review and make it into a blog post by taking a screenshot and posting it to Instagram. The developer of the app will be happy.
Here's what I wrote: "Floating Notes Lite is handy. I'm using this app to make screenshots, among other things, it's very useful. See how I'm using it on Instagram @pjbrunet
Feature requests: Often the note window is too wide or too tall to see something important. Also I would love a "thin" setting to shrink the "O" and "X" controls. And I wish the floating circle (minimized) "icon" was smaller, sometimes it's in the way."
