Jigsaw Block improved interface

I've been interested in the Jigsaw Block for a little while. I'm curious about how you'll make it usable players (Or if you ever will), so I thought of some useful additions to its interface.

I want a this because we can't currently use the Jigsaw Block, and the current interface doesn't feel complete, so I feel like we could add more to it before it's complete.

First of all, we need a way to activate it. A "Load structure" button would be helpful, but I was also thinking of something similar to the Command Block interface, in which you can control how it interacts with Redstone and other Command Blocks. The Jigsaw block would have 3 activation options: None, Redstone, and Automatic. If it's set to none, the block is just for show, as it can't load anything in without use of the manual button. If set to Redstone, it will load it's structure in and break down into its "Turns into" block when it receives a Redstone signal. If set to automatic, it will load a structure when it's loaded in by a Structure Block (Or another Jigsaw Block), then become it's "Turns into" block.

A "Probability" option would also be amazing. It would allow you to control the likelihood of your Jigsaw Block actually loading in a structure. If the block is loaded in by another Jigsaw Block, the "Probability" option will control how often this specific structure is loaded in by others with it's "Attachment Type".

Thanks for reading.
