On the Open Orders beta, the option to add park and unpark buttons have been removed and so has the generic 'print invoices' button that picks the invoices based on the template printing conditions. They make life a lot easier than having to go through the right-click menu.
If we could have them reimpletemented then we will be close to being able to use it.
Both of these action buttons are on the roadmap to implement.
Glad to hear. Your live support made it seem like we weren't going to get it and had to request it.
