To be able to pass on more information to the voucher's recipient it would be very helpful to be able to edit the layout of the voucher or at least have two separate (HTML) text fields for the Hotspot's homepage and the voucher itself.
At this build (9.003-15) you can only have one text which can be HTML and displays correctly at the Hotspot's homepage, but without any layout (plain-text like without formatting) when "printing" the Voucher's (PDF). In most situations where the connection procedure to WiFi (eg. company or hotel WLAN) is not seamless - when SSID and encryption key information have to be passed on - and even worse you have this information in more than one language - the voucher's text is unformatted and merely "unreadable". Passing on HTML formatting to the voucher's PDF for me would be sufficient.
