I did, but I also applied with the old application kit so I didn't have the same guidelines to follow with regard to what kind of proof to provide. Our entire application was over 300 pages because we basically sent copies of anything that tied us together physically in terms of receipts, tickets, etc. I had the same concerns you did.
My husband drove to visit me, so finding proof for those visits was slightly more complicated because he didn't have any tickets for bus, train, plane, etc. and they never stamped his passport (or mine, when I crossed, for that matter). We had copies of the travel insurance he purchased, fuel receipts from along the way, and then receipts from the stuff we did together while he was visiting, even if it was just a receipt from when we went to buy groceries at Walmart or his credit card statement with things on it that were obviously from time spent in the U.S. We also explained some of that stuff in an in-depth way in the part where you explain the development of the relationship.
I'm not entirely certain how I'd approach it using the new kit. My husband and I have both looked over it and agreed that we didn't feel like we'd be able to adequately prove our relationship (to our satisfaction) with the criteria they ask for now.
My visits to my husband were equally important to the development of our relationship. I'm not sure why they want such a one-sided view in that regard. We were fortunate in that we were able to alternate visits to each other for the most part, but I can imagine situations where the applicant might be the one visiting the sponsor much more often, due to either job or kids or education.
Ultimately, provide what you can and try not to worry too much. If they want more proof they'll ask for it.
