Heading back to Ukraine with the Ukrainian wife in a couple of weeks

Last time I was there was 9 years ago so I am wondering how are Borispol's Immigration & Customs proceedures these days ?
Previously I have never had any trouble at Borispol and as I remember it one used to front up to Immigration first, go through, collect one's bags, fill out the Custom's declaration then front up to Customs then out. ( pretty much straight forward except for the waiting in lines bit

)
I have my visa, and no registration is required although I seem to remember a strip of paper with ads on it one had to fill out and keep ?

Do they still have this ?
Any info / changes on Borispols Immigration & Customs proceedures these days would be greatly appreciated. ( as they say forwarned is forarmed

)
Many thanks,
