It's interesting, for sure, but I'm not buying that this is much better than just setting up some extra columns. The two arguments presented against extra columns are 1) editing time and 2) space. 1) Editing can be sped up, albeit with a learning curve, so maybe I can see that one. At least at my proficiency, I doubt I'd be saving any material amount of time. I can think of scenarios where this would actually be slower for me. People with less experience in spreadsheets might find some time savings, it's hard for me to gauge that. 2) Space, on the other hand, I'm not really buying. You replace extra columns with a wider column and a bespoke UI piece on the right-hand side. I can see columns A:H in the column example, and columns A:B in the final Ambsheet example (which, funny enough, is displayed as a 2x3 spreadsheet -- why not just have those 6 cells right in the sheet?). This also seems much more difficult to do visualizations from. Graphs, conditional formatting, etc. But that part isn't discussed, so there may be a solution for that which isn't shown. It's interesting enough that I would enjoy playing around with it. I very well could just be entrenched in my habits.
