RH-CustomBook (Support book with command)

Ever looked for a Plugin or Skript which opens a Book with a single command?
Here it is^^
This is an easy example with 1 page and a little text.

You're also able to configure a command in the left upper corner.

Here's my example (the download version):

If you click the on the page your command will be executed.
default command is /store.

Note:
I just made this as example how to use.
You can find other (and more) examples here:
