@Ron_Shultz you can set columns as Yesterday, Today, Tomorrow. day after Tomorrow… Next Week, Next Month, etc. if you have access to Rules (Business license) you can use the newest Due Date Approaching trigger to shift tasks between columns. Here is the announcement fo this new feature: New triggers for Rules: “Due date is approaching” and “Task is Overdue”
Otherwise, yeah you would have to manually move tasks between columns if the intention was for those to reflect when things are due. A bit tedious. I’d suggest repurposing columns for other purposes and rely on the built in filters to only show tasks due today, this week, next week, etc.
Columns/Sections can be renamed but there is no way to associate them to a hard due date. Milestones are essentially just major points of progress in a project that can be viewed form a Timeline or Portfolio.
