A large portion of the rest of KDE is editable to a rather deep degree, however, when the rounded corners change occurred it is impossible to make certain widgets have a corner radius other than 5px without doing the aforementioned change.
A visual change such as this should be an exposed setting not necessitating rebuilding from source, especially since the corner radius unit acts independently of the theme selected.
That’s if you use Klassy. You also need to patch and rebuild breeze if you want to unround the corners in that.
As much as I love Klassy, it might not always be available, so I don’t know if it makes much sense to only allow users to configure Kirigami corners unless they are also able to configure corners in their desktop theme, or at least, in the stock KDE desktop theme, be that breeze or union or whatever.
yes, I too would love to see this; also in the same setting vein : settings to disable corner radius entirely . I’ve seen another thread in which someone wanted to turn off even the default minimally rounded corners . even if KDE couldn’t give the option to pick any radius you wish (like in Klassy), the options of “off”, “default”, or “more” would be AMAZING .
