Before 2.8, the "gizmo" or 3D viewport axis viewer at the top right of the 3D view would never disappear if the user were to translate, rotate or scale an object. This would allow my students to pick and choose which axis to constrain to with a lot more confidence. The constant display was a good guide to allow people to be a lot more spatially aware during transform operations. This feature does not remove the hidning of the gizmo but adds a toggle inside the user preferences to allow people to choose between if they want it or not, I understand people sometimes dislike the intrusion of having the gnomon visible at all times.

Please do keep in mind, this is my very first commit to Blender, I wanted to give myself something very simple and if ever anything needs refactoring or changing, please let me know!
