thanks, however it is not exactly what I wanted, the projects are still there, and I need always switch the filters. Also to mark as reported works only after I save the report to my comp. There should be an option for each project in Time entries panel just to mark as finished with one click and not showing anymore in time entries but somewhere in old, archived project.
But for now I can live with that filtering, if there is no will to implement such a thing. At least let's hope the author listens to us, customers, who paid for this software.
