In terms of areas for improvement in AppSheet, I do many things with it, and I'm happy with its data features. The solution has good data features, and though some basic functions may not be there, AppSheet is good enough for me at the moment. I can use it in my business. I like it, and I'm still happy with it because I'm not using it intensively. I just use AppSheet for simple tasks rather than complex ones, though the solution has many use cases.
In its next release, what could make the solution better would be more partners for integration, for example, integration with SAP, particularly plugins or APIs with more partners that it could integrate with. There should be an out-of-the-box feature built for integration with more partners.
