upgraded 13.2 to leap 42.1,
using wolfi repos, I'm running KDE 4.14.17 and plasma 5.6.0, KDE frameworks 5.20.0, KDE applications 15.12.3.

Am i missing something or in [systemsettings>workspace theme>desktop theme] lack the custmize button??
the one that in the past allowed to customize the selected theme applying for example a theme to the widgets and another to the buttons...
