Hmm, I wonder. There are just so many possiblities of what can be done, and my brain can baloon with ideas fed off that. In the mean time, I know it's most important to scratch the itches with the most value, first.
Off my operating environment, the more pressing lack is notes taking. Simplenote works but via Android, I seem to be in need of writing my own client (been a while since I've hit that part of my GitHub). One thing that might be of interest is some client side integration, of being able to mate Simplenote, Blogger, and G+ and apply a little meta-search magic.
