Hello, I’m new to GNU/Linux. So, I don’t know many basic things. I’m using Plasma DE. I tried to make everything dark by applying themes from global theme setting, then from application style, I tried to make everything transparent and blur. But these dark themes and transparency effects does not works for everything including softwares (like CodeBlocks). I also tried Kvantum Manager to make everything dark and transparent, but failed to make it happen. I also followed some YouTube videos, but some of the settings options were different from my version.
If anyone wants to help a noob like me, then it will be really appreciated.
