Sorting of user names AND Hide "Start Progress"

Hi there,

i have two litte questions:

1. is it possible to change the way user names are sorted ? For example if want to assing a testcase to a tester, the names in the dropdown are sorted by the first name. Which is basaically the way I entered the name in the "Full name" field e.g. Jon Doe. It will be sorted by J not by D

2. is there a way to hide the "start progress" button within the testcase, since we are not using it and it confuses the testers ?

Thanks
