All views created inside SCSM are stored in management pack. The best practice is separate type settings (like class, relationship etc.), forms and data available in console (like lists, templates and views). But very often all that settings are saved in one management pack. And when you try to edit such management pack using Authoring Tool you can be in trouble because Authoring Tool require loaded all sealed management packs which referenced from management pack which is editing.
The good news: Advanced View Editor 2.0 for SCSM 2012 will be available at the end of this week. The bad news: will be available two different versions: free (Free Edition) and paid (Pro Edition). Get more information below.
