Autowalkers are really hard to make even in bots...You need to create something called a "web" which basically creates a virtual web of key locations you can walk your character to. If I were to make an autowalker, I might as well make my own damn bot
If you really want one though, as Runecrafting said, feel free to learn a .NET language and make one yourself as a plugin
Do you think you will ever add script's to the client? Making it more or so anm ease of use and cheating client? Will it completely be free....I was thinking more or so you can have a version that's free and a paid version. One for basic needs and another one with some built in scripts....
My only suggestion (something that would make it or break it for me) is to make an option so everything can be hidden apart from the runescape game screen.
