Please let me say how much I like this program.
I have used Package Factory to produce a U3 version which on the whole works a treat. However, there is one area where it isn't seamless. When keynote remembers the last file being edited it appears to do so using the full path including drive letter.
Only, as I'm using it on a U3 USB the letter keeps changing. If there was a simple option or preference to say don't use drive letter in path it would always work.
A very minor change, but it would make a big difference when using on a U3 stick.
