When using the editor to move objects around the scene, it would be very helpful to have grid snap increments of 1 unit for move and rotate. Currently the smallest increments are 5 for both. It would also be helpful to be able to use the arrow keys to move or rotate objects in 1 unit increments.
This comes up all the time when I am building a scene. The current smallest grid increments are sometimes too big, and so I need to enter values manually in the properties, which can be a bit slow and tedious.
