LL Navigator does not provide all functionality that is present in the standard Livelink / Content Server browser view. Will this be extended in future releases?

No, LL Navigator only provides basic functionality that is used 80 % of the time. In case users need to access functionalities that is not frequently used (e.g. check permissions) they can open the standard Livelink / Content Server view from within LL Navigator (and also increase the size of the pane) by clicking on container item like a folder or a project in the navigation tree. This will then display the standard Livelink / Content Server view in the right hand pane.
