Show HN: I made a spreadsheet where formulas also update backwards

Hello HN! I'm happy to release this project today. It's a bidirectional calculator (hence the name bidicalc).

I've been obsessed with the idea of making a spreadsheet where you can update both inputs and outputs, instead of regular spreadsheets where you can only update inputs.

Please let me know what you think! Especially if you find bugs or good example use cases.
