The unique identifier of the feature. The identifier must not exceed 38 characters in length.
The default level of the feature between 0 and 32,767. A value of 0 will disable the feature. For any installer there is a set installation level at install time. The initial value is determined by the INSTALLLEVEL property. A feature is only installed if the feature level is less than or equal to the current install level. The default value of INSTALLLEVEL is 1. During installation the install's install level can be set from a dialog with the SetInstallLevel control event. You should usually set the level of your features to 1 unless you plan on supporting different install types such as "Typical, Minimum, Complete, etc."
You can also set install levels of a feature conditional by defining conditional levels. To configure conditional levels, click the Conditional Levels button to open the Condition Levels dialog.
For more details about install levels see the "Remarks" section of the "Feature Table" MSDN Online topic linked to below.

You should only allow advertising for a feature if it contains a component that has an advertised shortcut, class, AppId, TypeLib, etc. or if your software supports install on demand through the MSI interface. In fact, if you do not have an advertised item in a child component, advertising will not be allowed anyhow.
If checked, the feature will only allow advertising if the operating system supports it. You should generally leave this option on. This option is only applicable if Allow advertise is checked.
If checked, the feature will be marked to be advertised by default. This option is only applicable if Allow advertise is checked.
If checked, the user will have the option to set a feature to absent in the user interface. If unchecked, the feature will be forced to the installation state whether or not it is visible in the user interface.

Favors installing the feature locally.
Favors running the feature from the source (usually network drive setup by an administrative installation).
