Excellent app but... User must switch tables or backout of the current database to force app to ask user to commit changes. If you back up to opening dialog or exit app before committing  changes are lost. App should provide a commit button or other proactive ui to commit and should warn user about losing changes before any action that would drop changes  e.g.  exit  occurs. A minor improvement would be to increase the list font size or at least provide the option.
