Nice!

i do not use any gtk4 apps

Its a fork of Lite XL (https://lite-xl.com/) called Pragtical (https://pragtical.dev/)

The colorscheme I am using is Tokyo night storm. GTK theme and icons are in AUR. However for icons I use themix (from aur) and suru++ aspromauros (also in aur) to creat the icons

For xfce4-terminal use an existing template like https://github.com/catppuccin/xfce4-terminal/blob/main/themes/catppuccin-mocha.theme and change the colors

you could rinse and repeat this for any app you want to style

Thanks! Tiling mode screen attached

Thanks

Pragtical (https://pragtical.dev/) is a fork of Lite-XL. I like it better than vscode
