I want to squeeze NLA editor and Dope Sheet on Y axis to fit more objects in one screen.
For example in VSE this can be done via CTRL + MMB and dragging in prefered direction. Same thing in NLA only works for X axis or stretching timeline. In Graph Editor it works in both ways, but doesn't affect list of objects, so still lots of scrolling.
Another thing I tried, was pressing NumPad's - while hovering over the interface. In some parts of it font resizes well (like Render or Object tab), but not in NLA - it just hides all rollouts.
