The Condition Block!

I'll list and organize my ideas:

The Function:

The Condition Block when used opens a display like a command block but it has a text box in it where the player can type who they want to allow to build in that area instead of everyone being allowed to build in that area, and multiple names can be typed in.

How it could work:

It works almost like a deny block and a structure block on corner mode. This means you'd need 4 Condition Blocks on each corner in a square with the same information, maybe even add a name bar in the display (like naming a structure block) so you can specify the area further and make sure there's no glitches!

The Looks (optional suggestion):

The Condition Block could look like both a deny block and allow block are merging together since it has the same functionality as both but is more specific.

The Why:

This would be great for people making maps where they would want an area or areas for specific players to build or break things in but not allow just anyone, this also helps prevent griefing! Then for areas they want absolutely nobody or everybody to access they can use Deny or Allow Blocks!

The reason for the name:

I think "Condition Block" makes sense because its condition is checking for what player is allowed to build and break things in a specified area via the text box inside it.

Important notes:

- The Condition Block should only be able to be opened and changed through someone in creative mode with operator, like the command block!
