Block Anchors

I suggest the implementation of a redstone based tool that will allow you to anchor a block, causing it to be immovable by slime\honey blocks, all while maintaining the original or similar aesthetic of the anchored block.

Big redstone doors making use of slime and honey blocks work well, but don't always look nice due to a lack of immovable blocks, as most do not fit the color or texture palette properly.

As such, this tool would allow some blocks to become immovable. I suggest that it would show a bright symbol on the anchored block when the tool is held, the symbol would then disappear when the tool is put away. Similar to how a barrier block works when held and viewing a placed one.

A simple click on a block would suffice. I'm unsure if it should consume any item to successfully anchor the block.
