Calc: Structure box of Structure tab in Function Wizard is very narrow

It’s very narrow when formula is very long. Using such tiny scroll bar at the bottom of the tab is not convenient. Where can I send the recommendation to ?

Noted with great thanks.

I have reported a bug time ago UI: resizing function wizard only resize the formula field, not the structure and parameter fields width
