updated at 2013/3/14: R.I.P Google Reader.

Google Reader改版了，是好是坏众说纷纭，总之原来那些分享的文章变成冷冰冰的数据包了。在Google悔过之前，我们总不能对着这一个个数据包发呆吧，特别是突然想找什么老文章的时候。所以在大牛 @isnowfy 的启示下有了这个小工具^_^

需要说明的是针对的是“阅读器 JSON”这种数据包，比如 shared-items.json 和 starred-items.json。搜索框里回车可以对标题进行搜索，列表框里单击可以在右侧看到详细信息，比如url地址和去html标签后的网页内容。去html标签使用了BeautifulSoup，所以请自备 BeautifulSoup.py在同一目录下 BeautifulSoup4。由于对Tk（Tkinter）这个古老而恶心的GUI不熟悉，界面上请不要苛责了^_^

附上使用图片和脚本：
