Great job Andrey!
I'm sure that this kind of users approach is much appreciated all over the world.
I really don't understand negative/bad ratings that appeared lately as I found it one of top 5 Joomla extensions outhere.
It seems to me that they were written by inexperienced people or some other irrational reasons.
I give my thumbs up to the developer who is doing great work! Keep on rockin'!
For me the best thing is that it supports Extra Fields import, since importing Extra Fields straight into the K2 database field isn't that simple.
Also I was very surprised how responsive developer was when I had a question which I sent to him through email.
Keep on with good work Artur!
