I made a tag on my Custom NFT Dashboard #forkme to see all the dashboards that are forked from it. Looks like it has been forked over 100 times and not one person has changed the default NFT contract (which is the only parameter it takes). Changing 1 parameter requires forking every query and then re-adding the new query to the dashboard. I realize it is probably pretty difficult to implement but just wanted to make the suggestion.

You can also see that was their original intention based on how the forked dashboards are titled.
