Switch button/command for command block

As an old Minecraft user that plays since 2011, I am really not happy with the new "Update" that the command block has received. I'm sure that a lot of other users feel the same but just don't express themselves about it. 

I really like the idea of changing things up, but you should consider giving the players an option to enable the old command block's functions. 

We used to have the "One command block" codes that were AWESOME to use! But now they are (sadly) unusable because of the new command blocks... 

Tried really hard to work with the new one's and I just don not get them.

I think it would be easier to just make another command block called "old_command_block" or something to keep the oldies happy!

Otherwise: nice updates, good changes, I love it.
