I've been looking for task tracking / planning software with some project management features, like the ability to decompose tasks into subtasks, estimate duration and priority and specify dependencies among tasks. However, the software I tested only allow duration to be recorded if the task is scheduled on a specific date, and they're usually complicated with a lot of features I don't need (yet). So I'm still using a bunch of spreadsheets for now...
