每周一次，我们打开小费盒，分享你寄来的好小费。本周我们将讨论如何在Windows7中轻松设置多个墙纸、快速浏览iBook以及跟踪应用程序价格下跌。

在Windows7中加载多个墙纸图像

HTG读者Abhijeet没有使用第三方应用程序来旋转你的壁纸，而是给我们发了一个链接，指向他关于设置你能想象到的最简单的壁纸旋转系统的教程。如果您选择任何一组图像，然后右键单击它们，您可以选择“设置为桌面背景”。如果您有多个图像，它会自动将它们设置为每天旋转一次（要加快旋转速度，请转到桌面背景菜单中的幻灯片放映设置）。这是一个非常聪明和未充分利用的方式来旋转你的背景图像没有额外的第三方工具的开销。感谢分享阿比吉特！

通过手指滑动快速ibook导航

安东尼写了一篇关于使用苹果iBook软件的小贴士：

I’ve gotten pretty comfortable reading books on my iPad (it’s no e-ink screen but it gets the job done). One thing that I’ve always been annoyed by with ebooks is that you can’t easily “flip” from one part of the book to the other. It turns out I was just overlooking a feature in iBook. If you tap the screen to bring up the navigation controls a dotted line appears across the bottom of the screen. Swipe that line and you can “flip” through the book at lightening speed to any page you want.

这似乎是一件很容易忽视的事情。你说得对，电子墨水屏幕（比如Kindle的）很漂亮，但是在Kindle上，仅仅从书的一部分刷到另一部分并不容易。谢谢分享，安东尼！

追踪ios应用价格

格雷格分享了他为免费和廉价应用打分的技巧：

Earlier this year I discovered a service called AppShopper. Prior to AppShopper I felt like I was always just missing great deals on iPhone and iPad apps (like a $5 app I’d had my eye on was on sale for $0.99 but I missed the sale by a day). AppShopper let’s you make wish lists of applicati*** you’d like to buy and then alerts you when the app drops in price. You can even get an actual app for your phone that pushes notificati*** so you never miss the updates. Since I got the app and started my wishlist on AppShopper I’ve scored piles of apps for free or $0.99 (when the original price was $5+ or more).

I haven’t been able to find a similar service for Android so if you know of one I’d love to hear about it!

AppShopper是一个很好的资源和应用程序，让你不断更新是一个额外的奖金。至于一个跟踪Android价格的网站，我们很想找到一个类似AppShopper的iOS应用程序。目前看来，最好的办法是AppBrain的新价格变化部分。其他人有好的以Android为中心的资源吗？
