Hi!
First of all. Forgive me for being late to answer this. There is no way (that I know if) to get a mail or whatever when a new question/issue arrives on wordpress plugin site – and I don’t check this page so often as I should apparently)
Thanks for your compliments. It feels great to know you think it’s useful!
So to the actual question. The short answer is no, but I like to please all users of my plugin so it’s possible to achieve. BUT I really need to know what you mean exactly.
Do you mean that rows (not columns?) should’nt show if a date is older than a specific date?
