setting to receive an email once a day. Depending on the task, I would like to receive notifications at different times: 5 minutes, 10 minutes, 30 minutes, 1 hour, 1 day, 3 days, etc. Please allow me the freedom to set this up. I think this feature is essential in task management. I forget my tasks very easily, so this is a must-have feature.
Also, the language seems to be English only, but please add Japanese.
Japan is a country of manufacturing industry, so this product will be familiar to Japanese people.
Also, if at least non-English input is possible for field names, etc., it would make the use of this product smoother.
