messages between blocks and other features

Permalink
Hi,

I have some dudes about concrete5 blocks in version 5.7.x.

Is posible to send message from one block to another block? For example, have one block with request some parameters (dates or something) and then send this parameters to other block with a php report that refresh the data report with this parameters?

Is posible to hide the first block, and then show the second block, in the same page?, taking the previous example.

Is some plan to do blocks that works like magic data in previous version of concrete5?

Thanks,
