Steps to reproduce:

Create new filter through Tools > Message Filters > New

Actual results:

When creating a new filter, you can configure the query, but have no way to preview it. In order to built confidence in a query, you need to use the search tool and the "new filter" window in parallel. See e.g. attachment "Screenshot_2023-11-27_10-19-54.png".

Expected results:

Instead, the filter window should have an option to preview the Emails to which the filter would apply.

In the attached example screenshot, it isn't that difficult, but sometimes narrowing down the query with 5+ criteria is necessary, at which point this workflow becomes somewhat painful.
