To be fair customization is a good thing, the problem is it's too easy to accidentally get into too advanced settings. It feels like the settings most people want 95% of the time are burried in the same place as the niche settings. The gnome tweaks app often gets criticized because it contains basic settings, but I think it could be beneficial for plasma to have the same thing. Only keep the base level user settings the the settings, and put all the customization stuff in a separate tweaks app. The simple by default, powerful when needed moto is true to some extent, but the simple by default part could be much improved and a lot more intuitive
