New window instead of new tab when viewing a page from the new page tree
Opening the kontextmenu in the new page tree and selecting the "show" item opens the page in a new window in Firefox. This is ugly since I want a new tab.
In the 3rd frame on the right if i do the same in the docheader of the page, the page is still opening in a new tab as expected.
can this behavior in the page tree be changed please?
