I want to make an extension that will swap predefined proxies in my google chrome (portable, but figures its all the same). Now the main feature should be it works automatically and its easy to edit, as I change the proxies sometimes. So it would either pull them from a .txt file (in random order) or have an interface where I can remove old/insert new proxies.

If nobody here has the time/will to write something like that, could you at least point me in the right direction? Some API, similar app or something

Thanks and have a great day!
