What a useful app. Reminds me of Airtable in some ways. I enjoy a good flexible table app any day. We're all tired of the obligatory "I wonder how long before Google deprecates this...;)" but I wonder if Google would get better adoption if they explicitly published what would be needed for them not to drop the product... 1M monthly users? 3M? ...xM? or that when a project actually reaches that point.
Once the distinction between products with long-term commitment and experimental products is super clear with a uniform icon/logo then there'll be less disappointment and upset future customers
