Although I am not currently using Invitex on my site I am very interested in suggesting some improvements to make Invitex as an essential part of EasySocial (The best social network for Joomla). I know you are working in Apps but I also want to suggest you for future versions de possibility to add IMPORT HTML option for templates. This option is available in other components as Acymailing and it is very useful to build your own Responsive HTML mailing template and to use it with acymailing.
Is there any possibility to do this currently with Invitex?
How can we add an HTML responsive template?
I attach you the HTML template that I currently use with Acymailing
Best Regards, and congratulations for your job!
