On this tab, you specify the options for the profiles. You only need to specify the options which are different to the standard options.
After making some changes, you must click on Save to save the options for the profile. You should do this prior to changing to another profile; if not your changes will be lost.
In the grid, options are identified by their internal option name. In many cases, it will be self-evident what option these corresponds to. For more on the internal name for options, see Technical Notes on Options.
