Way to keep hopper windows open half way

[thingsweregood]

I'm looking for a way to adjust how open my hopper windows are - currently either they're fully closed (with the latch), fully open, or I can adjust the amount they're open using a rolled up piece of paper towel wedged in the side of the window. Is there a more elegant solution!?

A hardwood wedge in one side. Sized to hold the glass roughly half open.

I use,a door wedge, can be moved up or down for variation on how much the window is open.

My hoppers would be less rain-proof half-open compared with fully open or fully closed (I think).

A bit uncomfortable. “You didn’t want to do that!”
