While Apple’s productivity apps (Pages, Numbers, and Keynote) have a plethora of native markup-like tools, the company’s other apps that can contain images-Photos, Mail, TextEdit, Stickies, Notes, and even (in macOS 10.14 Mojave only) Messages-can now employ markup tools. You don’t have to open the image in Preview to avail yourself of its special markup tools, and then copy or otherwise use the altered version. Have you ever had an image that just begged for a speech balloon with a snarky comment coming from your spouse (or baby), or needed a villainous Snidely Whiplash handlebar mustache added to your boss (or baby)?

Second, the programs were written in the AutoHotkey language, and programs created in this language are often frequently flagged by antivirus software even though they don't contain any virus. I have made these programs available through my research group's website and sharing something with a virus in it would not be very good for my career! First, you can be sure there is no virus or trojan in there.
