In order to properly track timelogs in a project report on a monthly basis one must manually move all completed tasks from last month out of the project folder (or create a new project every month which requires moving uncompleted task to the next month project) to see timelogs for this month only. I realize that this really only affects retainer projects that renew every month but I know a lot of people have repeating or retainer projects. This feature request could also help people who want to automatically archive projects as well.
It would be extremely easy for Wrike to implement a function that says:
If xTask in xFolder has been completed for xDays or at xDate (like the end of each month) move completed task from xFolder to x[Archive]Folder. This would be extremely easy to implement. The same function could be done for Projects.
This would let us decide when and where completed tasks (or projects) in a folder need to be moved. It's really very simple and I bet the API could do this now if someone wanted to take the time, but it would be best as a core feature.
