Another small quality-of-life improvement: hide the green box for the SQL prepared statement by default. Instead, I could imagine some small icon that allows one to toggle this box. Perhaps this button could be positioned next to the AI bot, or some other spot.
There are often times where I have to access controls below the SQL prepared statement, and I'm getting tired of having to click away the box first.
Besides, it doesn't really add anything in my opinion. I can see my query, why should I want to see it twice. Also, just seeing the placeholders, marked by dollar signs, is not that helpful and quite frankly, possibly confusing to some.
I think it mainly serves to give users insight in how the query gets constructed, but I feel like users shouldn't have to be concerned with the implementation model, unless it actually starts to affect them (e.g. trying to use variables to replace table names or column references, which is not technically possible due to PDO).
Long story short, I think leaving some of these technicalities in the background might help users in the long run.
