Looking to make a GUI for this config with pyqt 5/6. Will be opened by pressing a button. Modal. ``` # config.py from dataclasses import dataclass from qt.core import ( QWidget, QVBoxLayout, QLabel, QPushButton, QLineEdit, QSpinBox, QHBoxLayout, QComboBox, QColor, QFrame, ) from calibre.utils.config import JSONConfig #
