Just a quick update to let anyone who might still be hanging around know that I am slowly starting to work on the project again. I've reached the midpoint of the semester, and things are slowing down a little (at least until they speed back up at the end again). I don't have a lot of time to work on it, but I've been fixing some bugs and thinking about what I want to do next.
I considered turning the project into a Windows 8 application, but I don't know if I'm going to be able to make that work the way I want...and also decided that it might be too restrictive to move away from the standard Windows desktop environment. At this point, I don't want to create a program that some people can't use just because they haven't upgraded their operating system.
That being said, though, the final product *might* require users to have Net 4.5 installed on their systems, if only because I'm using Visual Studio 2012 for development now instead of Visual Studio 2010. I am not 100% sure of that, though.
So, there is definitely some work going on. Just not a lot of it at the moment. There will be more in the future, I hope.
