Sleekshot

This screenshot tool is made just for Windows 10/11 and lets you take and mark up screenshots really quickly. Right after you take a screenshot, you can start editing it because the editing area shows up around what you've captured.

The tool looks modern and comes with themes in dark, light, and a see-through glass style, making it look cool. You can add arrows and notes that you can move around and change how they look. The notes can have a background color so you can see them clearly on any picture. It also has other handy features like drawing boxes, lines, and using a pen to draw smoothly.
