One of the KDE Plasma features I use almost in daily basis is the MouseMark.
Go to your settings, in Desktop Effects, Enable the MouseMark (you can change the settings of it in the button in front of it). Then press Meta+Shift and move your mouse to doodle, or press and release Meta+Shift+Ctrl to define beginning and end of an arrow (it will draw the rest.
Interestingly enough, it have been in Plasma for the past 16 years:

You can, and also @flameshot provides more tools and colors, but it is a “still frame” because Flameshot captures the screenshot first, and then let the user to annotate it. Therefore it is not useful if a video is playing in the background or slides are changing or moving through the code.
Side note:: I’m one of the maintainers of Flameshot ;) and I’m glad you have found it handy :ablobcatattention:
