Yes, this is sorta for my own purposes to find features for my add-on but this is honestly a serious question. What should a BB Code Manager do? List your BB Codes and allow you to edit them and nothing else? BBCM takes this one step further by following the XenForo way and allowing PHP Callback, but what else should it do. I've always felt some of the managers I've used have lacked features. I feel an Import / Export is important, and will be adding it, but what else should it do?
