Currently when you are writing a query with parameter values, you are prompted for the values when you run. This works as expected.
However, if you modify the query, these values are reset and you must reenter them. When working on a query with multiple parameters this gets a little frustrating and tedious.
I have created and commented in the issue tracker but that was for Intellijj. Seeing as this forum is more focused on the specific database functinality, I wanted to add this feature request here for added visibility. See this issue for more details and the expected behavior.
