I did not see a forum specific to the Calendar app, so going to ask my question here. I am currently in the trial period, and setting things up to see how I can make odoo work for me and my company. So far, so good. 

What I am wondering is I see no way to set a buffer in the appointments (between appointments), and I don't see any way to charge for my appointments, is that because I do not have a subscription yet, or are these features not available in the Calendar app?
