SUMMARY
When creating a task in Task View, only Due time can be set, but Reminders can only be set relative to start time.

STEPS TO REPRODUCE
1. Open Merkuro Calendar and switch to Task View, click Create button to create one.
2. Set a Due time in 2 minutes.
3. Add custom reminder 1 minute "before start of event"
4. Wait until task due time is passsd

OBSERVED RESULT
No reminder notification

EXPECTED RESULT
A reminder notification should be sent at the specified time, probably by changing tasks to have a start time instead of due time, or support reminders that are relative to due time.
