It is about a limitation related to the new subtask list displayed on the left side of the task view, introduced recently in ClickUp 4.0. First of all, this is a very useful feature. Being able to see the full task–subtask structure while working inside a subtask significantly improves orientation and navigation within complex tasks. However, there is an important limitation: In the left-side subtask list (task structure panel), it is not possible to change the order of subtasks. To reorder subtasks, the user must navigate back to the parent task and adjust the order there. This breaks the workflow, especially when working deeply inside subtasks and managing task structure iteratively. From a usability standpoint, enabling subtask reordering directly in this view would make task hierarchy management much more efficient, especially for large, multi-level task structures.
