The tool bar is unneccesarily large and floats over the document. Although it is possible to move it, needing to do so every time I want to see the top left corner of my PDF is frustrating.
Overall there is a lot of bloat and pointless white space on all the menus and side bars, but especially the page side bar. It takes up a quarter of the window area automatically and there is no clear way to change the settings about autolaunching it or prefering a more compact version if it does autolaunch.
