I'd like to center my elements to the alignment I want, But the only thing I found was Height and Width.
It is extremely hard to align parts on the left or right, Is there a feature included on the toolkit? Thank you.
Centre/centre the screen, or use an arrangement and do the same. There is the Absolute Arrangement block as well, but this has a display bug in the companion app. You can also use empty labels and arrangements to position othe components.
