Hi @LuckyTigerr, thank you in advance!

You can start in color_sliders.h in the struct item declaration. The ui::Entry correspond to the 'entry' on the old way:

    struct Item {
      bool show = false;
      ui::Label* label = nullptr;
      ui::Box* box = nullptr;
      ui::Slider* absSlider = nullptr;
      ui::Slider* relSlider = nullptr;
      ui::Entry* entry = nullptr;
    };

Some reference can be taken in the following commit (when the input expressions were implemented): f595cee
