Scenario: Imagine a kanban system and some tickets in it (Like Jira, Trello, etc.)
The user can add various information to a ticket, such as assignment, description, checklists, etc.
There is a time slot input where the user can add the hours they've worked on that ticket. As soon as the user adds the time slot, they will not be able to delete this ticket anymore.
My question is: Do I just not show the Delete option anymore? But then the user might start to look for it, and thinks there's a bug if they can't find it. Or, do I leave the Delete option, and the user gets a pop-up warning with an OK Button?
I'm not sure if I need to try to avoid warnings/alerts that they cannot fix - on the other hand, hiding an option which is usually available is also not very user friendly. Any advice?
