KConfigWidgets:

• KStandardActions T12148:
  • Move somewhere else outside KConfigWidgets
    • KRecentFilesAction requires config
    • KRecentFilesAction uses KSelectAction but incorrectly?
• KCModule T12150:
  • It's a QWidget, there's also KCModuleQml, do some inheritance or composition thing
    • or move every KCM stuff into KCMUtils?
• KCodecAction:
  • Kate has its own, merge?
• KColorScheme T11587:
  • Why in kconfigwidgets? Needed all over the place
  • Add some features to QPalette (like positive, negative, neutral colors)?
    • Check if Windows, macos, Android, etc have semantic colors
  • Does it need KConfig? https://phabricator.kde.org/T11587
• KColorSchemeManager:
  • a widget with a model of colors and something to set custom color scheme
  • Split model and setting logic somewhere else?
    • Make it a standard action for them menu?
  • Needs "system color" option to reset custom color D25877

KRecentFilesAction T12246:

• Get rid of KConfig, store INI in some state home dir instead

KConfigDialogManager

• Remove redundant KConfigDialogManager::KConfigDialogManager(QWidget *parent, KConfigSkeleton *conf) and KConfigDialogManager(QWidget *parent, KConfigSkeleton *conf) See(D26361 T12480)

Move everything related to showing and providing config to KCMUtils.
Make KConfigWidgets be widgets using KConfig (ktipdialog, KRecentFilesAction)

Once all executed there's not much left. Kill it?
