Helm provides commands for easily aligning components. These are located in the Edit menu and Right-click menus.
There are two sub-menus Align Horizontally and Align Vertically.
Align Horizontally lets you align the Left sides, Right sides or Centres of components or also Distribute objects at an even spacing.
Align Vertically lets you align Tops, Bottoms, or Centres or Distribute objects to achieve a neat layout.
