Hi?
I think that it can be usaful feature which is like below.
Please consider this. Thank you.

(1) If I check "Doit Now', the task's start time becomes current time. Then I can see it on Google Calendar time table (daily or weekly view).
(2) If I enter spending time on "Daily Review", the task's end time becomes start time + spending time. Then Google Calendar time table shows the task's schedule.
