Today I played the game without having access to a mouse, so I had to resort to using my laptop touchpad. And since its scrollwheel-emulating feature didn't work, I got stuck with trying to play without a scrollwheel.
It was very annoying, as I could only zoom-in/out using the +/- minus buttons. But only the numpads +/- worked, not those on the digit row. Again, it was on a numpad-less laptop, so I had to fiddle with the Fn key. Yay. Furthermore, the +/- keys only work on the main map, not on the tactical screen. So I was unable to zoom-out to see the full tactical field. Double yay. Finally, the zooming using the keys is painfully slow, so quickly switching between the normal map and the cloth map took way longer than when using a scrollwheel. Triple yay.
I didn't expect Elemental to be friendly to play on a touchpad, since its interface is very mouse-oriented, but I didn't expect the absence of a scrollwheel to be the main issue...
