@jakehop I actually did not know this one existed!
I typically just used the left / right shift arrow when the widget to move is selected. Depending on in which type of section a widget is, this lets you move the position of a widget up/down left/right.
The buttons in your screenshot will sometimes not allow you to do what you can accomplish the above cut’n’paste-method, so that’s why it’s become my preferred workflow for solving these types of layout issues.
