OG Features aims to allow group owners and site administrators to disable certain features/functionality within a given group (without the use of the Spaces module).
What is a feature? A feature can either be a normal feature created by the Features module, it can be a custom module used to bundle existing components (views, node types, etc) of your site into OG features (toggleable entities), or it could be any module that introduces functionality for groups (like, OG aggregator, if integrated correctly); so, OG Features, does not require the Features module. A Feature or module can provide one or many OG Features.
If a user has adequate permissions, and there are toggleable features available, a tab will appear on the group labeled "Features" which provides a checkbox to enable/disable each feature for that group.
There is also an administrative interface, that allows site admins to configure each available OG feature to either be toggleable, always enabled, or always disabled, per group node type.
