Is there a GUI to set preferences for things such as double-clicking title bars in apps such as Remmina and (Color picker) Gcolor3?

I see Plasma / KDE GTK Configurator · GitLab but I can't tell whether that can do what's required.

(FreeBSD 14.0-CURRENT here.)

Background



For months, it bugged me that the preference set in Plasma was not respected by GTK 3 applications. Eventually, Google helped me to find:

• https://www.manpagez.com/html/gtk3/gtk3-3.24.31/GtkSettings.php#GtkSettings--gtk-titlebar-double-click – I don't treat manpagez.com as definitive for things such as this
• the path to settings files at Mega Tutorial para hacer que un sistema GNU/Linux funcione más rápido | Trastetes – it's not ideal to voyage through Español to discover what's required, but that's where Google took me

I manually added what's required to ~/.config/gtk-3.0/settings.ini … for future users, is there a GUI to simplify things such as this?

As a sidenote, kcolorchooser instead of gcolor maybe? One gtk app less that gives you a headache.
