No RAML details in apiworkbench

This a bug that that details pane is not visible?
According to this documentation http://apiworkbench.com/docs/ if I go to Packages -> API Workbench -> Open RAML Editor Tools I should have details pane. Yet nothing like that happens.

It also does not suggest commands, does not underline errors in commands… does really nothing. Like windows notepad. This is normal?
