Thank you for the appreciation. Personally, I can't live without i3, and you can always have plasma installed as well; there's no need to choose between them. If you're new to the concept, I started with Regolith to become more comfortable with i3. Technically, you can use my Polybar and Rofi on plasma if you just like their appearance : )
Thanks, colours are based on the wallpaper. But yes for gtk I used catppuccin for the similarity
