Clinked consists of many great features. Overall, I wish they would do a complete re-design, but keep the features.
My 2 favourite features are the overview of all tasks and the overview of all groups. In particular, the overview of all groups gives me access to see what projects are running off track and what is on track. This means we can tackle issues and communicate it to the client in an early phase of the project. This is sooo powerful, I can't emphasize it enough. Keep up the good work!
