@user1823, what about the latest commit?

[user1823]

When is self.allow_to_past True and False respectively?

[L-M-Sherlock]

When the user applies easy days for specific days, it's False.

Ok, it is acceptable.

However, a better solution would be to also create new fuzz ranges when pressing Apply easy days now and when Auto apply easy days on closing collection runs.

If the above is difficult to implement, I am OK with merging this PR as it is.
