How to modify the startpanel in stylebuilder

before long i'm starting to use stylebuilder, despite simple interface, its numerous values still puzzle me a lot... it sucks....

as shown in the picture, the proglist is so long that there is still much space left, which in my opinion is pretty ugly, i don't know how could i fix this problem?

(it's said that under value/general/startpanel/proglist, the width and height are defined in the defaultpanesize,i change the figure,but it doesn't work)
