While there is tab Shared With Me in web interface, you may and should put shared by me tab too so that we can instantly find shared project and in case we forget to unshare when we need not to give details, it is very much handy and in fusion desktop app, in project explorer where we see all our projects, there should be indication beside project name of shared icon so we can get idea that this project is sahred and we can decide weather keep it shared or un-share it.
