To align or distribute object, just select more than an object and use the property inspector, it will change this way:

It permits you to:

  • equalize object widths to the longer one
  • equalize heights to the longer one
  • make heights, widths and position the same for all selected objects
  • align left, right, top, bottom, center (horizontal), middle (vertical)
  • equally distribute horizontally and vertically
  • move them with extremely precision
  • change the layer order in the current card

To help you to align object, you go to Edit->Preferences->Apparence, there you can set alignin grid data (spacing, colors, etc.), then activate it on View->Grid. Now you can move object only on the "virtual" gird.
