No orphan sub-tasks in list views

When viewing issues as lists and showing sub-tasks, sub-tasks are not necessarily kept on the same page as the parent. (See the attached screen shot). I would like to suggest that it would be better to display sub-tasks on the same page as the parent, even if it means exceeding the number of issues to be displayed per page. Either that or provide a toggle that allows for this limit to be exceeded when their are "orphaned" sub-tasks. Thanks for considering this!
