Full appointment process in widget area

Hi there,
Regarding Appointments+ plugin:
It would be great if the user could set an appointment directly within the sidebar (or a pop-up that could be open from the sidebar) and not from an other page.
In my case the appointment is only a part of a larger process and I don't want my user to leave the context of this process.
A beautiful responsive widget/pop-up to do so would be really appreciated :slight_smile:

Thanks again,
Julien
