Async and await
Async and await like .net.
Access as an application that connects to remote data (sql server or web apis) and then freezes on every call makes no good user experience.

Yes!!! The "Not Responding" comment is to understand for a user. But coupled with the color change of the form to fully white, that is so annoying and does not look very professional. Fix this white screen form.
