SOFTWARE/OS VERSIONS Windows: macOS: (available in the Info Center app, or by running `kinfo` in a terminal window) Linux/KDE Plasma: KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
Maybe I am missunderstanding your report but the tools in the toolbar do not take over the the opacity from each other. Selecting the paint tool and setting the opacity for the brush is only valid for the paint tool but not for other tools. Holding shift or not does not make a difference in this regard. I think your request is a feature request, not a bug report.
