we have o2m of ~6 levels and at the bottom ie 6th level all earlier #5 parents path should be seen at the top.

we are using atk/themes/stillblue.

The top actionpagewrapper are constructed from stillblue/templates/actionpage.tpl. Here atk shows previous #3 stack levels ie prv #3 parents. we changed it in actionpage.tpl to show all #5 prv stacks ie parents.

But the PanelTitleText still shows prv #3 stack levels (ie prv #3 parents) only. Which tpl controls this? we checked almost all tpls but could not guess.
