It would be neat to see some themes for Home++ (or options) that change the look of the bottom buttons. There's not a whole lot else going on that would warrant entire themes being developed for it, though. I like it just fine right now the way it is.
Yeah I know a lot of people prefer Home++ for the simplicity and how well it runs. I don't want a lot of bells and whistles, and I like Home++ for those reasons as well, but an option for themes would be great also.
