This has been mentioned before, but has it been addressed? If so, then I can report that the measures taken were not enough. New tasks are still placed "randomly" within its group in the list. New efforts will be necessary to make this clean and nice.

For example, if you drag a new task to Next, and have it grouped in some order (e.g. deadline or context), then the new tasks now will be auto-sorted to some random position within its group.

What I would prefer is that all automatic placement within groups be based on VISIBLE parameters only, such as Priority - never on invisible parameters such as last edit date etc. I also suggest that the placement within a uniform segment of the group (for example within a priority stratum) always be done consistently either at the top or at the bottom of that stratum - never randomly in the middle.
