Another item I noticed:

When you are in the Settings screen, and hit the escape button, it pops up a dialog asking of you want to Save Settings, with the following options: Yes, No, Cancel. Selecting Yes does save the settings, but only makes the pop up dialog disappear. It does not take you back to the main Search screen, which is usually what is intended by hitting the escape button. Selecting No actually takes you back to the main Search screen. Cancel makes the pop up dialog disappear.

A feature I would like to see, is to be able to use this app with multiple desktops ( e.g. my home computer and my work computer), without retyping in the service identifier each time.
