Is any further information available about how the app works before I authorise it to act as me on Twitter (change my profile, post tweets etc...)
Unfortunately, permissions are only configurable on a read only or read/write basis. Since this app changes settings, it has to have the read/write permissions. I don't save access tokens, so it reauthorizes every time you click enable/disable. I just posted the code on github for anyone who's interested. Here is the link to the code that messes with your twitter account: https://github.com/willcosgrove/retweet-rip/blob/master/app/...
