great … I was waiting for new version of ccloud… can we have selective sync like that of skydrive?

Status bar doesn’t give clear idea what’s happening… on hover only thing I get is ??? sign

Thank you for this release

The feature is already present with CB.
In CCloud it will be introduced in a future version.


The issue will be fixed in next release (4.2.1)
