  Let's be clear, I don't think one uses the projectmanager to do complex navigation in which you need to an overview of the entire tree layout in front of your eyes. Rather, you navigate a project with it, the general layout of which you presumably know rather well. In my own typical use I tend to work mostly in isolated subparts of a project, where I find it very useful to be able to align the project tree inside the toolview so that I have the most effective view of the contents where I can access the files directly.
  I agree that the structure of the KDevelop project itself (KDevPlatform included) is particularly complex which probably stresses any project manager to its limits.

  2 different applications, and both type of applications usually provide both keyboard and/or touchpad zooming + scrolling (and more and more webpages seem written to use the entire width of my screen without taking window width into consideration ... and the browser doesn't even provide a scrollbar).

  The same applies to the tricks required to figure out how to see the entire filename, or have them resize the toolview continuously.
  As to setting up the touch/trackpad, I think that's something we should assume that users will have done so the equipment works "optimally" for them.
  As far as I'm concerned that includes having disabled horizontal 2-finger scrolling if that doesn't work for them, because that same feature will cause the same trouble everywhere if you cannot master it.
  Still, I'm trying to write a wheel event handler that will filter out the horizontal component from the events unless we know they come from a scroll wheel. For now I have managed only to achieve the opposite :-/
  FWIW, I didn't want to propose making this a configuration setting, but apparently that's where we headed.
  And note that this whole discussion applies to scrolling with a touchpad. Users with a mouse with a scroll wheel don't have this problem; the wheel scrolls in 1 direction at a time only (on Mac the system or Qt generates horizontal scrolling when using the wheel with the Shift modifier).
