Version 1.6

• Fixed: Fence gates, signs, banners, and doors can no longer be turned into footprint blocks.
• Fixed: Footprints no longer destroy flowers, saplings, crops, and other fragile blocks growing on dirt/grass when the block underneath is replaced.
• Added: allow-special-blocks option in config to control whether blocks with special effects (magma, slime, cactus, etc.) can be turned into footprints. Default is false.
• Added: hide-footprints-for-invisible option in config. When enabled (default), players with the Invisibility potion effect do not leave footprints. Footprints resume once the effect expires.
• Fixed: Pressure plates are now properly excluded from becoming footprint blocks.
