On Mac/Cocoa, horizontal and vertical scrolling are equally smooth, and that's where I did most of my testing (while replying to this ticket).
  
  
  For me it's not so much about smoothness. It's rather that scrolling in both directions happens with the same speed. That makes sense for images, but for scrolling through a directory tree you might want to have much less sensitive horizontal scrolling, while still being able to scroll fast vertically. I guess Mac OS does that. But this is not something we should try to fix in KDevelop.

  Indeed, even the class view has horizontal scrolling. I'd say the case for elision is even stronger there, because that hierarchy isn't going to be very deep. (Though I don't know how deep people nest their name spaces...)
  
  An another note: I was just using Thunderbird and noticed that they are eliding not at the end, but somewhere in the middle. Could this be a solution? Suppose you have files `projectmanager.cpp` and `projectmanagerview.cpp`, which are both abbreviated like `projectmanag...` right now. Instead we could abbreviate them `proj...er.cpp` and `projec..ew.cpp`. A disadvantage would be that we waste space for the file ending, which is already encoded in the icon to some extent.
