BeforeDo PicFloater

If your work involves capturing several screenshots on a daily basis, you probably understand that Windows' built-in features are somewhat limited and might not provide you with the best results.
However, you can try various third-party tools such as BeforeDo PicFloater that can help you perform your tasks quickly and provides you with satisfactory results. It is worth mentioning that you need to grant Administrator rights to this app if you want it to run as intended.

Lightweight screenshot utility

You can turn to this program if you need a quick way to capture screenshots on your computer without significant efforts. After launching the app, you simply need to press the "PrintScreen" key on your keyboard and select the area you want to capture.
The program lets you choose between capturing an object on your screen by simply selecting it (pay attention to the outline it draws) or manually define an area by dragging a rectangle shaped box.

Rudimentary toolbox

After you perform the screenshot, you will notice a small toolbox next to the captured area that contains a bunch of components, designed to help you create annotations or highlight certain parts of your image.
For instance, you can draw a circle or rectangle shape on your picture, write some text, and draw an arrow. The colors of the objects can be customized by selecting the desired ones from the toolbox. You can also change the font of the text.

Pin or save the image

Furthermore, you can choose between saving the resulting image to your computer by clicking the floppy disk button and specifying a destination path on your PC or pin it to your screen.
Pinning the screenshot creates an image object directly on your screen and lets you move it around freely.

Lightweight screenshot tool with image pin support

To wrap it up, BeforeDo PicFloater is a portable app that can be used to capture screenshots with ease. It lets you decorate the screenshots with customizable shapes or text and save the resulting image to your PC or pin it to your screen.
