How do I enable an addon for all but one file in Blender 2.7b?
A more tangible way to express my query would be that if I have 4 Blender (.blend) files, A, B, C, and D, then how do I enable an addon for A, B, and C only but then not for D?
Basically, how do I make the User-Preferences for one file different from the one in others without re-modifying them (the User-Preferences) again every single time on startup? (And no, I do not mean to "save different startup files". Explaining one last time: You know how there is a button which saves the user's prefs for all Blender files? Well, how do I save them for all but one file?)
