One of the most common complaints about OneUI 7 in discussing forums was the lack of quick panel customisability;currently there are small 1x1 tiles, larger 1x2 buttons which many people do not find useful, and large media and brightness controls. Both Pixel UI and iOS offer significantly more control over this menu.
A better system would allow users to resize any quick settings to either be a small tile in the existing area or a larger moveable button, with any unwanted buttons being able to be deleted.
