In the next release, I think that it would be good to have wizards that would update into specific applications, for example, a one-touch configuration in Pagemaker.

When we need to find the queries there is no user interface, it is the only textual format that is bulky. If we need some data we will use Athena for queries and we will get results. When comparing this solution to others, such as DataDog, they provide a wonderful UI, and user-friendly dashboards, and many other features that this solution is lacking.

We need the mapping to Windows. That feature is needed in S3. That feature is in the Azure cloud where we can map it like a drive. We can map the cloud storage to the effort driving our Windows PC. But Amazon is not providing that feature for the S3 solution.
