description by Petr:
At present the grades appear in the gradebook immediately. Even if hiddenuntil used, the grades are there, there is no way to delay the appearance of grades from activities. This is especially important for activities like quiz where teacher wants to release the grades only after everybody submits. Technically we would keep the grades in rawgrade until some time or manual confirmation by teacher. We would need a new flag in grade_items table indicating the type of activity-gradebook integration:
- none - grades entered via gradebook reports only
- legacy - overridable with plusfactor and multfactor
Teachers would have topknotsome UI to see all the grades in buffer. We would need a new gradebook report for confirming of grades.
