+* What kind of NON-image data do you need to make your “viewer” work?
+* What kind of labels and descriptions do you need?
+* What kind of data relationships are needed in order to make it work?
+  * (For example sequence: what comes first, what comes last, what comes next?)
+* What were the pain points of making an image viewer this way?
+* What felt repetitive?
+* Were there features you built that you wanted to re-use but couldn't? How come?
