Im using Unreal engine for our latest project after years of using Unity, and am really liking it.
I didnt think this would be the main issue i would have, but im finding moving objects around a level frustratingly awquard compared to what im used to in Unity.
The main trouble im finding is being able to move objects around on a given plane similar to how you can in Unity by dragging the central square around. I know its also possible in Unreal but only if i zoom in and very preciesly drag RIGHT in the middle of the square.
9 out of 10 times ill drag the central square of gizmo to move an object around on the ground plane and instead it will move it either up or down! 
(i dont have snapping turned on
Are there any addons available that improve this at all? or am i just doing something wrong?!
thanks for any help
