Make the Formula Builder Field Picker Width Bigger

Hi -- just building up some formulas for a new data object and realized how difficult is is to pick the right field. My formula takes "total today" - "total yesterday" to get a value for how many actions took place over the past day. But, as you can see below, it's tough to tell what field is which. The hover works, but it's slow. And there is just SO MUCH WHITESPACE over there to the right!

So... here's a request to make the field column much bigger. :-)
