Excel, but linear, without the reference mess. It looks cool for mocking up dashboards. Some form of grid with nested documents could make it more useful.
+1 this! I think writing helps you create a narrative that disambiguates the mess you can create in Excel. It also forces you to think more about what you do.
Good suggestions! Thanks
Easy on the features, though. If you make it too complex, it can lose its (fairly) unique proposition of simplicity.
