One-hand three finger (text select, dictionary lookup, file and window drag and drop) and four finger (expose up and down, virtual desktops left and right) gestures are great on MacBook trackpad. At some point they were default in macOS but now I need to reenable them on every install in both trackpad and accessibility settings. Especially the tree finger one (point + middle + ring fingers) is so much better than click and hold to drag.
