Sub Forms in Custom Fields once Joomla 3.6 arrives

Are there any plans to support the new "Sub Forms" field type in custom fields in both Event Booking and Membership Pro in the future when they arrive in Joomla 3.6 next week?

Right now, the two extensions use it own custom fields implement (as it needs some special feature like custom fee fields...)

However, yes, there is a plan to build a form builder library which uses Joomla core JForm to replace current custom fields implement in my extensions

Not sure about the time yet but we will have it in the future

Regards,

Tuan
