Size hint is a new widget in the DevTools library that allows you to easily take a screenshot of your current viewport. It is a useful tool for making sure a webpage is responsive, but it can also be used to take a screen shot of a specific widget.
Size hint is an app that, like many others, allows you to take a screen shot of your current viewport with a click of a button. It allows you to take a screenshot of a page, then automatically resize the screenshot to be half the height of the screen. I’ve been using it to take screen shots of all my widgets, including the one above. The widget also lets you save a screenshot to a folder, which I use often for screenshots of the page I’m working on.
