We can include the contents of any field in notifications, emails, invoice, certificates and other

But it is very difficult to know at the time what is the string for each field ...

We need something that shows column or list, what are the strings available,

I do not remember in additional to joomla I seen it what, but something like this:

When entering setup an email to notice eg

show all options, fields and everything else that already appear

but also arises the left side of the screen with a list of all string fields that can be used for personalization of e-mail

I do not know if I can explain myself well ...
