It’s great that we have such fine control already, but it could be slightly easier.
Having the left and right arrow keys(by default) adjust the value of a box you have selected, for example the Z Position axis; By pressing left or right it would be adjusted by 0.01 in either direction.
This would apply to every box you can edit with a numerical value, having to re-type the last one or two digits of a value does get old after a while, especially with bigger projects.
