All the code is public if you are one that doesn't mind living on the bleeding edge of software. https://github.com/Blocthemes/TinyPortal
You are free to try it if you'd like. I'd advise running it in a test install to make sure it's working right for you.
If I remember right, if you want to install the new version, it will require you to uninstall the older version of TP before you can install the new one. Not sure I was through with those changes though....
If you really need the changes, and can't get them done yourself, you can post your file here to see if someone can help you get them in.
