The feature to mark specific coversation items as private is a great feature, but the implementation of it isn't fantastic - specifically the very small icon which is difficult to distinguish whether it's locked or unlocked. Would it be possible to change these images so that they were more easily recognisable at a glance - possibly by greying-out the public entries and colouring in the private ones?
Presumably these are images we could change manually in the interim whilst a change is being made by yourselves?
Here's a mocked-up example of the kind of thing I'm suggesting:
