It would be nice to be able to set an event on a ticket based on a date. Sometime, a customer send us a request, but isn't available for a few days.
We've to set this ticket to "Waiting", but remind somewhere that it must be managed later.
So, a bit like gmail does, it would be nice to have a function like "Remind me tomorrow", of "Remind me next week" which set the status to "Waiting", but automatically reopen it when the time has come.
I've tried to set a custom field as a date, but i couldn't use it in a workflow. And i dont' think that right now a condition could be base on a date <= current date. Which would also be nice.
