Hello!

(sadly the google map function in ICagenda don't seem to do that) What’s the sense to have a map if you cannot have the direction to the event - Nice but not really useful...

This is not because it's not a full featured Google Maps, that it is not useful for many users !
Some improvements are in the roadmap about Google Maps. (not today a date planned for development)

Chacapamac ha scritto: • I need the Description to be as flexible as a normal article & to be edited by the onboard normal editor (same that edit normal article) (JCE or other) - And be able to Insert module/social plug-in — Whatever

You already can since 2 years...
It's maybe due to an issue in your editor config, as for example, if you're using JCE, it's working fine with iCagenda description field!

Chacapamac ha scritto: • I need the registration form to be flexible
— You can add different type of custom fields
— Users can add personal comments
— Events registration even if register in Joomla administration have to be send to an email - each events can have different email

Personnal comments is already in registration form! (look at "Notes" fields, and if activated in the global options of iCagenda)
About custom fields, the 3.4.0-beta version with custom fields (and much more noew features) is currently being developped and tested by volunteer Pro users, since 2 months.
THe stable 3.4.0 will be release for all (free and pro versions) by the end of October.

Sorry, i don't have understood ?...
But maybe you're talking about the many email options available in global options of iCagenda ?

each events can have different email

This is already this in the "contact's email" field ?!?...

But i'm sure that since 1 month, you have already explored iCagenda, and found many of those options!
