-	// XXX should these be loaded as a ribbon/collection???

-	// 			- stored globally (config), locally (index) or something 
-	// 				in the middle (collection)?
-	// 			- how do we handle this collection .images???
-	//		...on the other hand a pure collection is a bad match here as it

-	//		which is a really bad thing...
-	//		...this could be done via:
-	//			- dialog w. previews (a-la metadata)
-	//			- floating ribbon (in a dialog)
-	//		this can be implemented as a hidden collection...
+	// XXX implementation vs. UI
+	// 		implementation:
+	// 			- this looks like a special collection with local .images
+	// 				- hidden?
+	// 				- can this be global or shared between indexes?
+	// 			- this can be just a list in .config or .data (global/local)
+	// 		UI:
+	// 			- this can be loaded and/or edited as a collection
+	// 			- this can be a dialog...
