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:

It seems the Github mirror is way out of date. I checked the https://invent.kde.org (the KDE’s Gitlab instance) and found out that during the past 6 months MouseMark has received some updates, especially about the logic of arrow drawing:

But as far as I can tell, even if you have the latest build from the latest source code, the general process of drawing is the same:

@Mehrad @[email protected] @[email protected] On my Desktop computer, running Arch Linux with Plasma 6.0.0, it works correctly. On my laptop with Fedora 39 and Plasma 5.27.10, it is bugged and doesn’t work properly (Both running under Wayland).
Anyway, a great feature! Thank you very much for pointing it out.
