Hi stwert,
You mean it is is just tricky to select? Try clicking on the arrowhead, it's a bit of a bigger target.
Thank you for your hint, unfortunately it does not help much! On a 27" monitor the arrow head is also not much bigger. The 3ds Max solution with the constraints, and, when the constraint is set, you can only grab an move the object in that direction you selected, is much better.
