I'm playing on Android both on tablet and on my PC via AMI DuOS. I play with a mouse because I find it much more precise, but I can't zoom on with it: on my tablets I got to finger-pinch, on my PC I've got to use duOS's shortcut (alt+ctrl+T, O, O, altctrlT). Being able to zoom with the otherwise unused wheel on my mouse would be nice, to quickly check both collectors level and base layout before attacks.
