Currently, the translation widget always faces the positive axes of the selected object. This can make it a pain to select two of the axes if the little multi-axis grabber square is behind another, e.g. when you’re looking along the positive Y axis and trying to grab the X,Y square, but it’s behind the X,Z square, making it hard to grab. Example screenshot.
This is a minor usability issue, but makes it difficult to properly place things in a scene, especially when building a set out of static meshes.
