Third Level Page + Priority of 2nd level pages

[mvlcek]

well, as I am expanding my test-site and creating more and more menu-levels, the i18ln-module is quite helpful
...
but unfortunately I see only 3 levels in the page-list, I cannot find a way to edit these pages

Unfortunately the standard pages view can't handle multiple navigation levels.
However, you can still edit and delete all pages (when you find the page you are looking for).
And there is the I18N view (also on the pages tab), which sorts the pages by title (as long as it's not Umlaute and other special characters).

Another view where the pages are ordered hierarchically (and can be rearranged) is on my to do list.
