While CyanogenMod is generally regarded as the biggest and best of the innumerable custom ROMs, some of the others tend to implement interesting additions to Android much sooner. The latest nightly builds of CM 11 (Android 4.4) have added something that's not exactly new, but should be very much appreciated by immigrants from other ROMs. Users can now long-press the physical or virtual Recents button to quickly open the last app "under" the current one.
We've known about Project Hera for quite a while, and at Google I/O today, it was confirmed by Google's Director of Product Management for Chrome, Avni Shah. Hera is a new way for the web and apps to interact with each other on Android via an API, allowing apps like Chrome and Docs to use multiple scrolling items in the Recents menu at one time. Combined with the visual overhaul in the L release, this may drastically change the way that users interact with content.
One of the fundamental differences between Android and every other mobile operating system is the practically unrestricted capability to run services. Without this freedom we could not enjoy something as powerful as a homescreen widget or as straight-forward as a Twitter client with background updates. Aside from games and very simple utilities, it’s becoming increasingly rare to find an app that doesn’t run a service, at least for a short span of time.
There are a lot of apps like SwipePad, and no matter how many we cover, I keep coming back to the original. Loopr is the first app in a while that's tempted me away, thanks to both an impressive visual presentation and some thoughtful features. At its heart Loopr is a a quick app launcher/switcher with the usual side-swiping mechanism, this time launched as a semicircle of icons similar to Circle Launcher Widget.
The virtual looping feature enables scrolling past the leftmost or rightmost homescreens with a quick bounce-to-the-opposite-end effect. While Fede implemented it this way instead of an endless scroll for technical reasons, I think it's visually a lot better and clearer, as you will still know when you've reached the end and won't feel lost in your own homescreen forest.
