As LineUp is about attention and prioritization, the ability to custom sort the LineUp task on PC, moving them up and down, makes much sense, as it helps to better prioritize the tasks that requires your attention. However this loses its practical significance and makes no sense if we can't view the lineup with the same sorting on the mobile devices. It is confusing and messy. You anyway somehow decide how to show those tasks in Mobile LineUp, so please sync this view with the PC.
