Shamelessly copied the Amphetype UI I know but at least you can add and remove books and also convert non-Ascii characters to Ascii so they are typeable which is what I wanted.

A couple of other options are in there too. Let us know if there's any features you want put in and I will do my best.

Binaries and source code at http://acutype.codeplex.com/ with a couple of screen shots on the home page.

Needs .Net 4.0 to run, haven't tested it on other machines.
