I can shedule many things in Elemental: unit building, facilities building, magic research...
But, except Magic, I cannot rearrange my queue. If I shedule pub - it will be pub, even if later I decide to build hut. Yes, I can remove pub from queue, but it is not good too - I need this pub, only later!
Magic have priority sorting, but here another issue arises: for some reasons, ironically enough, I can change order of planned things, but I cannot remove it from queue!
