Anchor Block

The Anchor Block is a feature that stops blocks from falling to the ground or move from any force, until the player launches. This can be useful in cases where the player is deleting blocks but does not want some blocks to fall. Having the box unchecked will make blocks fall when the block connected to the ground is deleted. It will also make ability blocks usable without sailing.

Trivia

 * Prior to the introduction of the anchor option, a block that was not welded to another would cause the block to fall and become loose from the grid. With the new update, now all blocks are anchored by default, but the player can switch it off by unchecking the "anchor block" option.
 * Front Wheels and Back Wheels will anchor only the gray block the wheel attaches to, and the wheels themselves will still be able to spin and turn.
 * This can be toggled by the Property Tool.
 * The ground is perma-anchored, so any blocks attached to it will not move or activate abilities when an attempt to active them is done.
