I know there is a patch that adds plenty of useful functions to the PDF reader on the Touchpad, but one thing that is lacking is the ability to highlight/write on the file (and save those changes). It's not a deal breaker for me, but my father is quite envious of his friends with their iPads and Android tablets that have this functionality. I'm in the early stages of learning JavaScript, so I can't do this myself. Is anyone up for the task? It doesn't have to be compatible with the above mentioned patch (I can uninstall it if it gives him highlighting). If it is possible, please let me know. And if you're up for the task, that's even better.
