My Idea: A plugin that white-lists adventure worlds for players, and will disallow the placing of blocks or breaking unless clay. It will also make a players inventory specific to the adventure map, and give a reward at the end of the map. When the player finishes the map, he/she will be automatically be teleported back to the survival map and the map will reset. The plugin will also have a waiting list feature. The waiting list feature will allow players to wait their turn for the adventure map when someone else will be playing. Also, a "group" can be formed. This is if the player wants to play with a "group" of friends. I know there are separate plugins that can do this all, but I need 1 plugin that can do this all. Why? Its too much trouble to configure everything on 1 plugin only to have it conflict with another.
