KvLibadwaita VS Kvantum

What is the difference between this and KvLibadwaita? (https://github.com/GabePoel/KvLibadwaita)

That's because i use this KvLibadwaita and adw-gtk3 themes to have everything looking the same on Gnome :>

You can also just make KDE look like GNOME with very little effort.

QT themes? This exists btw. I even have them change with light and dark theme with the extension (though i have to tell the extension to run a script to copy paste both kvantum and qt5ct.conf file to their respective folder with respective light and dark theme). Its complete baby.

There's a libadwaita kvantum theme

It's written in QT, so you need a QT theme. There's the KvLibadwaita style for the Kvantum theme engine.

Sounds like KvLibadwaita might be what you're looking for.

GTK Theme: adw-gtk3, KvLibadwaita

For QT you can use kvantum and this theme.

I'm using Kvantum engine with my custom Andromeda theme

I think Kvantum has support for theming both Qt6 and Qt5 apps now though so that might be worth trying if it bothers you that much.

The ones I know of are: Aurorae (built-in one), Kvantum (https://github.com/tsujan/Kvantum/tree/master/Kvantum) and Lightly (just a theme https://github.com/Luwx/Lightly). store.kde.org is down (at least I can't access it at the moment), so I've shared github links.

What about : https://github.com/tsujan/Kvantum ?

Make sure Kvantum is selected in the application style section of your look and feel settings. Read through the usage instructions on the Kvantum GitHub page.

Perhaps you can submit an issue

As for Kvantum, you'll need to either install it from your distro's repos if you're lucky, or if not you'll need to compile it yourself, you can check how to do that here.

arc-theme with kvantum look petty good imo.
