I do still have intentions to get another release produced as there are a number of developments I have spent time on that I wanted to release. One of the issues I've had is that a piece of functionality I included (deletion of empty directories) is flawed in its implementation. I am probably going to have to release without it and I don't think I will ever be able to include that without a full redesign. This may apply to one or two other tweaks as well.
At this point in time I don't want to make it open source as I still think of it as an open project of mine, but if at any time I decide I'm no longer interested in Car PC stuff at all then at that time I would probably release the source code.
