At the moment the options are just very tight, tight, normal, loose and very loose - all of which are pretty useless. 'Normal' is usually OK - standard - but if tightening is needed, 'tight' is too tight. This requires going even further than the drop-down menu into 'more spacing', which takes the OS a comparatively long time to open the dialogue box before you can enter the amount. On top of that, there is no option in this dialogue to preview the result - meaning you have to 'OK'/apply the new tracking value before seeing how it will look. If it isn't the desired effect, you have to do it again. Quite a painful process at the moment.
