Hi,
As the title says, I was wondering if there is a way to allow smooth zooming by holding both mouse buttons and moving the mouse if you don't have a scroll wheel, much as there is in (for example) Homeworld.
Not that I wouldn't like an excuse to buy a new trackball with a scroll wheel, but having a choice would be nice

The game itself looks great so far, looking forward to spending some quality time with it this weekend
