SUMMARY I am not able to resize the Kcalc window. It seems that it is stuck to a limited size. Neither Ctrl + '+' increases the size of buttons.SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: KDE Neon (available in About System) KDE Plasma Version: 5.20.5 KDE Frameworks Version: 5.77.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION I downloaded the Kcalc from the Discover store.
That's intended, because the size depends on the number of buttons (mode) and the button font size.
