Auto Suggest Variables in Auto Layout drop down

Have the variables drop down shown when free typing into any of the spacing fields. At the moment you have to select the variables icon on hover to access the available variables, but it would be quicker to have those suggestion shown as well you a user clicks any field and starts typing a value to be also be able to see the variables drop down shown to pick from.
For instance I might know I needs a sml or 16px spacing value, it’s quicker to activate the field and start typing because the field is a larger hit area then the small icon button to access the variables. It’s also faster from a tabbing perspective to be able to activate a field, type some values to see what variables I have available and then select the one I want.
Would even be awesome if I have a value in a field that is exactly the same as an available variable, that it would let me quickly attach and detach the variable the same way you can attach or break a style to an element.
