A very plain wish: When the focus is on the "Pages" panes ... it would feel natural to me to scroll through the pages with the cursor keys ... but by the looks of it there is absolutely no way to use keys to proceed to the next or previous page. Even enabling the "End" and "Pos1" key would be nice. Maybe this functionality could even be active if the the main window is active, you have the "Move" tool selected and there is no frame selected ?!
Aside that I find it very hard to recognize what is the currently active page. This thin frame marking it is hardly visible - even harder, when the content of various pages is layoutwise pretty similar. So it always takes this extra-extra effort to find out on what page you are on in the page panel.
Cheers,
Timo
