Marked Hidden Blocks

Some blocks look almost exactly like harmless ones. This pack puts small corner marks on them:

• Red corners on every infested block (stone, cobblestone, all stone brick types, deepslate), in the world and in your inventory. No more surprise silverfish in strongholds.
• Orange corners on suspicious sand and suspicious gravel, at every brushing stage. Easy to spot in deserts, ocean ruins and trail ruins before you break them by accident.

Normal stone, sand and gravel are unchanged.

The textures are small edits of Minecraft's default ones, so the pack sits on top of vanilla or under any other pack. Minecraft's original textures belong to Mojang.
