在网页上批注，写评语，画重点，记下最精彩的文段及感想，永久保存至云端，是我们制作猫爪的出发点。
猫爪的特点：
1、任意文章详情页拖选文段即可标记，写点评；
2、重新打开标记过的文章，之前的标记/点评会重现；
3、数据永久保存在云端；
4、针对新浪微博和腾讯微博做了大量的优化，支持微博的点评和标记；
5、在百度及谷歌搜索时，插件同时搜索猫爪标记过的文章及点评，让标记和收藏真正的发挥价值；
也许我们成不了作家，但我们都能成为随手画写，甚至指点江山的评论家。让标记成为习惯，现在，使用“猫爪”。

Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
