This is not the biggest issue in the world but I feel that as you will be editing properties tens of thousands of times over the course of a project this basic functionality should be as smooth as possible.
In UE3 you could click anywhere on a property to select it, and change it. In UE4 you need to click on a very specific part of a property to edit it. This makes editing any property cumbersome to me in UE4.
The picture explains this best.
If you click the one pixel above or below the label, you can expand a section in UE4 by clicking on another place other than the little arrow, so it appears this is somewhat supported, but the label is claiming priority over the clickable area?
