what happens is this

first tab http://s10.postimage.org/eh6txxrrr/Untitled.png

 

scroll to the west, and go to second tab http://s10.postimage.org/p5akws1qv/Untitled2.png

scroll to the west, and go to third tab http://s10.postimage.org/lzukkb8if/Untitled3.png

 

scroll to the west, now i gotta delete browse tab...move new release + top albums to left..and add  top tracks tab.

what happen is this http://s10.postimage.org/t4cdtcfrr/Untitled5.png

 

why doesnt top track appear at the end? and it coincides there instead? I bolded the code part for my last action.

coz labeliefield browse is  6 letters, when i add top tracks its more letters...
