Recently, I found a plugin called “Currently” which is a simple Google Chrome plugin/extension that that adds a twist to your internet browsing experience. This plugin replaces the “New Tab” screen with a new one that shows the user the current time and the weather! The cool is that the user can customize it in different ways, for example the colors, layout and some other features.
I recently came across an interesting article talking about the @2x image in iOS. So to summarize that, if your app supports both retina and non-retina displays then you should include on image with a regular size for the non-retina display (ex. backImage.png) and another one with higher resolution for the retina display (ex. backImage@2x.png).
