Simple to use, nice functionalities (appointment calendar, Google Map and wigets addons, good ideas!) but ..... no way to customize the mail that is sent! No template available for that, the mail is just a soup of text, highly difficult to read. Only the appointement response mail can be customized, but only in plain text.
The config pages and the form display on the front-end are very user-friendly, the mail sent is absolutly not! Why this lack? I know that lightweigt is good, but a nice idea would be to let us choose the mail format (plain-text mail selected by default, for example) and to enable a template capability, not only for the appointement response... Some improvements would be very welcome ;-)...
For me, some another thigs are missing: the capability to add/remove fields (at least text inputs) and the possibility to select which field is mandatory or not.
I will keep track of future developements of this plugin.
