Can a similar app be published that provides all Sense users ( designers and developers ) insights into which features are available in which version and in which environment ? Yes you can Google a topic but often navigating around multiple documentation pages is not easy. The Insights app makes this really easy to do for APIs.
As an example in June2020 Sense gets chart sparklines. But it would be nice to see in an app with filter panes that this is from June2020 onwards, which chart types have the new feature, and also the fact that it's only for SaaS environments. The excluded values will show people what is not available.
Another older example is say the "duplicate" dimension/measure feature - first version ? Which chart types ? All Sense products ?
Aside from helping us all out ( customers and partners ), it may also help Qlik drive more customers to SaaS as more and more features seem to get added there rather than for QSEoW. This app would show the key differences in platform versions.
