+    # - add 'contact author' to report errors, etc
+    # - should edits to the server fact override local edits? (yes, easier
+    #   that way)
+
+    # - sync handling - do before standard sync, but don't touch deck modified,
+    #   so if last changes were done on server, stats will be synced properly.
+    # - if models/facts/etc don't have their modtime set to now, they'll be
+    #   missed by the standard lastSync check. so don't honour modtime on the
+    #   first time around, but honour it after that
+
+    # - sync period
+
+    # - handle subscriptions separately, or with sync?
+
+    # - how to easily remove subscribed cards? sort by modtime should work..
+
+    # - some models will be from a foreign source
+    # - append (foreign) to model names when created
+    # - two options:
+    # -- deleting a model will ignore any future cards from that model
+    # -- deleting a model requires the source to be deleted (models are
+    #    protected)
+    # - what will merging do? mapping from one model to another won't work if
+    # - the user has chaged the number of fields
+    # - want user to be able to delete models (and their associated cards),
+    #   without necessarily deleting all of the source's material.
