I don't know if I missed the thread dealing with this change and the reasoning for it but I don't understand the Track Browser was taken away from the View menu. As it is now you have to go on to the settings and it is (as far as I can see) dependent on which tab you have open, so for example if you have a tab open without the Track Browser it is unticked in the settings but if you have a tab where it is displayed and go to the settings it is ticked.
This behaviour seems very counter intuitive to me, the settings should be for global things and shouldn't be tab dependent. Aside from that it is quite annoying to have to go in to the settings to have to enable/disable it, it should be more accessible than that.
