There's a big difference between the status of a task and the task itself.
While a task can have different status like "to do", "feedback" or "completed" it can be of various nature (depending on the business, team size, etc.). There are lovely ways to categorise (and color) that with tags or custom fields in list view, yet ClickUp lacks the possibility to color the tasks in Gantt view.
Using the Gantt view as our planning tool, we would like to color the tasks by tag or custom field rather than have them change their color once they're set to "complete".
