I can't emphasize this point enough. Hypercard was an amazing tool, in the same class of evolutionary steps forward as the spreadsheet. It's unfortunate that nothing's come along to replace it. (I still have fond memories of Hypercard class in high school)

Relatedly, although it still exists, Apple Numbers is one of the few pieces of software that I really miss since my move to Linux. It has lots of subtle design choices that gently nudge you towards good data organization habits (e.g., If you keep an index column and title row for each dataset, you get rewarded with readable cell references).
