Hi， thank you for your advice !
We have special mark for uncompleted tasks.
In day performance: the orange part is for uncompleted tasks.
In day review: there's an orange ring besides the uncompleted task ； if the task is finished, it would be a green point.
Is that what you mean?

Thank you for you suggestion and support.
Have a nice day !

ahh okay but i meant a button to mark a task as "uncompleated"
For example: if a task like "sleep at 22:30hs" was not compleated. How much time the task will be as overdue? because i could not do that task, if i did not do it the night before at 22:30hs. So the only option would be delete that task. For that would be confortable the button to mark that task as "uncompletead" so it dissapear.

Regards
And have a nice day too! :)

Hi,
I got you ! It's a good idea.
Now we're thinking about making a form recording tasks.
For example, for a repeated task, I didn't do it today, then it's "uncompleted"; if I have done it, then it shows "finished".
So that we have the record of the task.
It's just an idea now, we would further consider it.
Thank you for your advice.
If you have more ideas, please feel free to tell us.

Have a nice day !

Thank you!
Have a nice day too!
