Hi HN, I noticed that many sites have screenshots of their app or site with pseudo OS X-style title or menu bars, but I can't for the life of me find what tool they use. Surely there's something out there to easily produce an image with it at the top.
For an example, see DuckDuckGo's whatsnew page that's on the frontpage today: https://duckduckgo.com/whatsnew
