Mid-air mod - is a mod that adds the ability to place blocks in mid-air for building.

A white outline indicates where the block will be placed (P.S. Press O to turn off the outline) 

By pressing B and scrolling the mouse wheel, you can zoom in or out on the location where the block will be placed. 

In the settings (ESC), there is a button that allows you to increase or decrease the maximum distance

The rotation of the blocks is also synchronized with the player's position
