Ability to re-queue failed sent messages (and, better yet, option to auto-queue)
If a sent message fails, it'd be awesome if I could simply re-send it as opposed to having to type it in again. Even better, I'd prefer that failed messages were automatically re-queued and tried again with the next message fetch.
When not in perfect conditions SpotX will attempt to send a message, alot of times the send will fail. We need to be able to resend the same message again when in more favorable conditions.
