Rewrote sidebar compilation code, caching is more stable now and things were cleaned up/separated into more functions/made plugin-expandable. In theory, plugins can add new sidebar block types now. I'd personally like to see a fully plugin-based sidebar editor that completely overhauls what Enano has now sometime now that this framework is in place.
