It is been improved but I still experience the following issues
1. check in option is always disabled
2. plug in manager shows red icon on the CC plugin entry, if this plugin is officially supported by Intelij then some changes need to be done so old plugin doesn't wipes out a new one
3. Which CC configuration is to be used e.i. Command line, native, new native etc.
4. What Clear case root means - it looks like it has no effect on any functionality
