(Bedrock) A few new things for map-makers, and quality-of-life changes!

New Command Ideas

/gamerule everlasting [boolean] - Determines if tools can always be unbreakable.

• Alternative: /enchant @s everlasting - Enchants any tool with durability properties (including small tools) with an enchantment called "everlasting". Useful for unlimited items in servers that provide them.

Settings Directory - Settings > Game > Default Permissions > Custom Permissions (where Operator, Member, and Visitor are located) > you then set your default permissions to whatever you want as if you were giving those permissions to every player. For example, you can have all players be visitors but be able to use doors and switches, and open containers.

Building Ideas 

Void world type - Sandbox world with only air that generates a 4x4 bedrock box filling in (-4,0,-4),(4,0,4) or (-4,-64,-4),(4,64,4).

Color Block - This block is a special block, which means it can only be accessed via the /give command. The block could be placed like normal while standing, and while sneaking, can be configured to be any color you want it to be with an RGB, Hexadecimal, or HSV system. The block is completely textureless, and the default texture would be a bright red that can be easily edited. The default configuration (let's say RGB for example) would be 255,0,0. There would also be a color picker with the block.
