Create/Open Book/Change Book

Hello how can i create a Book and let a client use it to open it or can i use OpenInventory?
and witch event is called if i the client chance the Content or sign it

The API isn’t finished yet, but this feature is planned for 4.0. See this github issue:

As a follow-up, there now exists BookView which allows opening signed books.
It is not possible to open a book for editing from the server because it is handled completely client side.

I now have an open PR for the GUI (Window) API

I don’t know of an event for changing/signing a book. If you need such an event then create an issue on the API repo
