🔖 Feature description

In the current edit task modal it is possible to set done and cancelled date to the task. I suggest that this kind of task is wrong and this should not happen.

✔️ Solution

Make the Apply button unusable while done and cancelled valid dates are present, highlight done and cancelled date input blocks with red.

❓ Alternatives

Hide/show done and cancelled date based on status:

• if status is todo, do not show either
• if status is done, show only done date
• if status is cancelled, show only cancelled date

At first glance this seems like a duplicate of:

• Edit Task modal: creating a task with both Cancelled and Done is possible #2986

Indeed, I duplicated myself, <facepalm/>

Hahah. And you even searched the "I searched previous Ideas..." 😉

The labels are pretty useful for those searches... (thanks for adding them)
