I have published Auto Respond 0.10 on the Play Store. Some of this was actually included in previous releases (0.9.2 or so), but I included all of it in this changelog.
• The Android SDK changed to make it a lot harder to have the menu setup the way I did, so I had to put everything into categories
• Added a couple new options: notifications are totally optional now, with an additional option for it to be permanent, and there is now an option for vibrate as well as silent
• Added more info into the JB style notifications
• Fixed a few small bugs
• Added "Cancel" to the long-press menu for the list of messages

The new version should be live in the Play Store as soon as the Google servers are updated (an hour or so usually.)
