I maintain a FeinCMS website containing more than 2000 pages. The page list contains a few list-editable checkboxes. Loading the page list takes horribly long (up to 20 seconds) and even much longer with JavaScript enabled.
It should be possible to load only pages of the top hierarchical level at first, and to fetch the submenus when needed with ajax. It seems there's no plugin or snippet published yet for this purpose. Is there?
