(1) In user's profile, medias are sorted by ID (see medias-in-profile.png). It would probably be better to sort them by type.
(2) Suppose we have two medias, one email and one SMS, defined as shown in defined-medias.png. We also have an action (see action-config-1.png) that uses our email media. We then disable our email media, go back to action configuration, and see action-config-2.png. It says "send to all" and "no medias defined", which is false and misleading, because we also have SMS media enabled. It would probably be better to say something like "sent to email" and "no medias defined or enabled" instead.
Note that same thing happens when deleting a media for which an action is defined. Something might or might not be done about it in 2.0 under database integrity changes. However, the issue will still remain with disabled medias, so let us do something about it.
