Version: (using Devel) Installed from: Compiled sources When I display a PDF, below the page area are two icons for next page / previous page. This icons are not part of a toolbar. This has some bad usability consequences: #1 When the pages are below the displayed page, they shrink the amount of space the page can use. Many (all?) Monitors are wider than tall, so this was a bad decision. #2 Beeing no toolbar makes it impossible to simply delete or disable those controls. Suggestion: either move them more to the left, below the page preview / table of contents display. Or make them a toolbar, so that one can disable the toolbar or move it around.
