it's the same for feedback, dashboard, api, ... -> all are hardcoded ... :(, if seen this after deeactivating the feedbackplugin
Duped by #999. See navbar patch.
I'll commit your patch for #999 separately.
The other half of this ticket is to suppress a disabled plugin's widgets in the dashboard layout.
in [1599](why did the trac not automatically put the message here?)
note that if ones disables all plugins, then go to the dashboard, adds a widget, all previously added widgets from disabled plugins will then be lost on dashboard layout save.
