Preserve history of moved/replanned tasks

For audit/review purposes, it would be really helpful to keep a “ghost” of the task in the original timeslot.

EG: I am supposed to complete “Task 1” from 14:00-15:00 and “Task 2” from 15:00-16:00 on Tuesday. Task 1 overruns, so I edited Task 1 to show that it actually lasted 14:00-16:00. Then I replanned Task 2 for Wednesday.

But when I look back at Tuesday, I only see Task 1. I don’t see that I was supposed to complete Task 2.

Even though I moved Task 2 to Wednesday, I‘d like to keep a greyed-out/”ghost”/imprint of it on Tuesday, so I can see what Tuesday was supposed to look like.
