In case anyone gets confused, Ctrl+T is a toggle. It flips back and forth between the pre-2018 interface design and the current one. In addition, there are two little icons in the lower left of the Drag-Drop area that can select the two choices. I don’t know that there are official names, but some us call the one with a larger Chordsheet area the ‘new GUI’.
