When you are making your redstone suggestions, please note that Java and Bedrock will not have the exact same the same redstone systems - this would require redoing redstone system completely on one platform or the other. The two systems are functionally different and are going to stay that way. Please be sure to tag your suggestions with (Java) or (Bedrock).

Lasers

One block which is laser emitter and another one named laser receiver. If placed on the same line horizontally or vertically, a laser appear between them (like the one emitted by beacon), if an entity or a player is passing through, the laser disappear and the laser receiver emit a redstone signal which one can be used to activate a command block, note block or whatever you want :D

 

I really think it's an awesome idea that can solve many things that I can't create currently like a lab, a security system a mob farm. Btw a second block called "powerful laser emitter" creating in this time a deadly laser with his receiver which kill the entity passing through the laser.

    Yes! And what if the powerful laser also broke certain natural blocks like dirt, wood, and stone.

    I would also like lasers that burn you if you try and go through them. This can be used for security.

    You could make the laser from a dispenser and just use the new target blocks as recievers. Functionally that could be useful and effective as an addition to redstone contraptions
