* Reduce the number of icons in the main toolbar (Open and Save were kept due to popular demand)
- we no longer use XMLGUI merging

* Order the zoom actions more naturally i.e. [-] 100% [+] like acroread (other KDE apps like oKular use [+] 100% [-] so there needs to be some discussion here);
I personally prefer [+] [-] 100% myself since I adjust zoom by pressing buttons quickly.

* Drop the "Zoom In" ([+]) and "Zoom Out" ([-]) text as the buttons' purposes are now dead obvious due to their positions. I am starting to hate this already because I have to aim very hard to press these small buttons.

This is based on feedback on my blog about "Text Under Icons" toolbars.
