Ask HN: New features for my Excel Add-In product ?

Hi, Back in the mysts of time I asked for feedback on my new Excel Add-In product and the response was awesome. Things are going well but I am looking for new features, new problems to solve with my next release. Of course I've had discussions with my users but I thought some of you might have good suggestions also. I'm looking for a new problem the add-in can solve. www.querycell.com is the product url. All suggestions appreciated.
