iLogger was originally derived from my "My Stuff" app. Last year I replaced the "My Stuff" app with MyStuff2. You can see the list of changes made on the MyStuff2 website at:http://www.maddysoft.com/iphone/mystuff/whatsnew.php
The tentative plan is to make a similar change to iLogger. Of course the Amazon integration won't apply to iLogger. And I plan on adding graphing support to iLogger. Nothing is definite yet. I'm still making some big improvements to MyStuff2 that will take a while to finish. Many of these additional changes will likely end up in the improved iLogger as well.
