The aim of this project is to write an RSS news feed reader program, with a "kill file". You should synchronise to the user's Google account to keep track of subscriptions, and articles read and not read.
The idea of the kill file is that the user should be able to mark certain topics as not of interest, so they are not shown in the list of unread articles. For example, I might subscribe to a "latest phones" RSS news feed, but do not want to see anything about iPhones, so I should be able to put "iPhone" in my kill file.
This project could be written for either a desktop operating system, or for a phone OS.
