Expand/collapse fields in debugger

The debugger is pretty good, but it expands all of the fields in every Thing automatically and there’s no way to collapse them.

So what that’s doing at the moment is it’s going like three Things deep, because Thing A has a list of Thing B which has a list of Thing C and there are like 300 Thing C’s so trying to view the fields in one Thing A creates a huge scrolling problem since the middle of it has a giant list of 300 Things that I don’t want to see.

If the fields, could start out collapsed, and then you click on a plus [+] to expand them, that would be more useful.
