DeadEye is an opinionated fast screenshot tool with a cheesy name modeled after macOS's own. It's still a work in progress, but it's perfectly usable.
This is not a fully-featured screenshot app with features such as drawing, highlighting, or uploading to an image host. If that's what you want, check out ShareX instead.
In Windows 10 Version 2004, Microsoft broke the built-in Win+Shift+S screenshot tool. Prior to that update, pressing this key combination would immediately take a screenshot and present the area selection UI. Now, there's a delay of roughly half a second between keypress and the actual screenshot, making it impossible to capture things that are on screen for only a split second.
As of Windows 10, Version 20H2, Snipping Tool remains broken.
Launching DeadEye will make its icon appear in the tray. Right-clicking the icon opens the menu:
The Settings window offers a few cosmetic options and an autostart option:
By default, pressing Shift+Alt+4 will take a screenshot and present the area selection UI. After selecting a crop area, DeadEye will put the cropped screenshot into your clipboard.
Pressing Shift+Alt+C will open a color picker. Clicking any part of the image will copy a hex color value like #ABCDEF into the clipboard.
