Okay, actually the reason I was confused is the web interface seems to be very buggy. W, for instance, seems to shuffle you back and forth between two units as often as it cycles through all of them. And lots of activities, like R or I, just leave you sitting on the unit you assigned it to, rather than sending you to the next unit waiting for orders.

Yes, there is some room for improvements in the unit controls. If you could please list all the bugs you find in unit controls, then I would be happy to fix it in the next version.
