The 
General > Capabilities preference page allows you to enable or disable
various product components such as Java development and plug-in development. By default, the page only shows general
categories of behavior. If you would like configure fine-grained capabilities you should use the "Advanced"
dialog.
Note: Some capability selections have dependencies on other capabilities, disabling a required capability while leaving dependant capabilities enabled will only result in them becoming re-enabled. This is the case when deselecting Java development and Core Team Support.
When attempting to enable an action after its capability has been disabled or has yet to be enabled in the preferences page, a Confirm Enablement prompt will appear verifying that you do indeed want to enable the required capability. Click Details to display a description of the capability.
Note: This dialog only appears if the "Prompt when enabling capabilities" preference has not been disabled.
