 Short term:
 
+- drop EntropyCacher.CACHE_IDS from entropy.client.interfaces.{dep,cache}
+- disable packagekit notifications (conflict with RigoDaemon)
+- settings -> fix repos_installed and repos_installed_keys, they could be stale
 
-- entropy.client.interfaces code refactoring (including inst_repo locking)
+- entropy.client.interfaces code refactoring
 - wrap available repositories usage around a ResourceLock, this will
   decrease the need for an exclusively held Entropy Resources Lock.
