SUMMARY *** I want to Spectacle this feature. Free marking of the area, for example by drawing with the mouse. You need something like this if you want to send pictures from the screen to social media and there are areas near the picture that you don't want to include.. I've seen this in a Windows system. *** SOFTWARE/OS VERSIONS Linux/KDE Plasma: Kubuntu 22.10 KDE Plasma Version: 5.26.4 KDE Frameworks Version: 5.100 Qt Version: 5.15.6
Spectacle has had this for a few years. :) Click the "Annotate" button on the bottom of the main window.
