I'm not sure that Puru is actually working on his Oxwall plugin projects any longer. I say this because I recently saw such a thing posted on the forum here:
https://developers.oxwall.com/forum/topic/49324
He has not answered me for a few weeks now, and some of my questions on his plugins have been clarification that could only take a few moments (and result in income for him with my purchase).
I know he has a history of vanishing though. It's kind of sprinkled here and there that he has long absences and then come back saying that he has experienced hardship and rough time. Maybe his life is very unsettled though and will be back once again. We can hope.
Until then, I have no idea what a "delete option" means. I'm not sure why this was posted publicly if you're not willing to share the update through private contact.
