Add EE 3 custom menu functionality
Fixed an issue in more recent versions of EE where the sidebar might not show up
Collective 2.0.0 is a major user facing overhaul for ExpressionEngine 3. It will not work with ExpressionEngine 2. However, the ExpressionEngine 2 version will remain in the downloadable zip file for a few versions so that if you need to use Collective with ExpressionEngine 2 you can do that. Collective 1.x will remain feature frozen even if Collective 2.x advances.
Collective 2.0.0 is not compatible at all with ExpressionEngine 2.
