This snippet can be used to hide the categories tab in edit mode (if you installation does not use EPiServer categories). Tested on EPiServer CMS 6 R2 but should work on older versions. 

Used for Product: EPiServer CMS 6
Code sample:

[GuiPlugIn(Area = PlugInArea.EditPanel)]
public class RemoveCategory : ICustomPlugInLoader
    public PlugInDescriptor[] List()
        EPiServer.UI.Edit.EditPanel.LoadedPage += new LoadedPageEventHandler(EditPanel_LoadedPage);

        //Never return a plugin - we don't want to add tabs.
        return new PlugInDescriptor[0] { };

    void EditPanel_LoadedPage(EditPanel sender, LoadedPageEventArgs e)
        if (e.Page.Property["PageCategory"] != null)
            e.Page.Property["PageCategory"].DisplayEditUI = false;
