Because the organization I work with had to turn off the notifications unless you are @ mentioned and because we work in different timezones I have to use email to schedule my comment replies for the next morning.
This is an issue as nobody sees my comments until they manually check.
So I think one of two new features would solve this but I'd love both.
1) Support @ notifications from email replies.
2) Add a "schedule comment" option directly in Wrike. So I can write a reply at 11pm their time and it doesn't actually post or send a notification until a certain time in the morning the user can select. This would allow me to work in Wrike and use the mention feature without it being immediate.
