How do you position an element in the center?

Hello, App Inventor newbie here.

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.

Thank you for answering, but aside from using empty labels to arrange, I'd like to put the other elements aside from the left element.

Use percentages of width
For example for 3 elements you could use 30% 40% 30% or 25% 50% 25%

Here are two places you can make such adjustments:

Inside Arrangements and Screens:

Wouldn't that work for labels or text boxes?
