It would be great if users could choose which cards to sort and leave those they either don’t know where to put or just don’t want to include.
On the same note it would be great if users could add their own cards… sometimes we think we know what users want but they want to add their own and that is valuable insights.
This was such a challenge for me recently. I ended up having to remove some participants with large miscellaneous categories because they were skewing the results. Would also be cool to have a feature where I could tag individual open sort categories to be left out of the similarity matrix.
