Google has been talking up Snapseed and it's enhanced HDR mode in recent blog posts and events, but the Gallery-based photo editor is getting a boost in Android 4.4 as well. This new editor will be shipping with KitKat, but it's also part of AOSP.
The layout of the editor has been tweaked a bit and has support for both phones and tablets. A lot of the filters and effects were already present in the Gallery, but it looks like you have much finer control over things now.
In my opinion, Photospheres are one of the coolest camera features of Android. I don't use them that often (not often enough, anyway), but I always take some new ones when I go visit my grandparents in Virginia, because the country up there is just too beautiful to ignore. These Photospheres give me something to look at when I'm feeling "homesick" for the place where I grew up.
As time has gone on, the team behind Photospheres has made subtle improvements with each Android version bump, and KitKat is no different.
Update, 11-6-13: We've added in all the relevant stories from the following week.
As you may have noticed, your friendly neighborhood Android Police writers have been more than a little busy in the last couple of days. Google had the odd notion of launching a new flagship device and a major operating system update on a holiday, so it's understandable if you haven't been able to keep up. If you spent most of last night escorting your kids around the neighborhood (or if you don't have kids, and you spent most of this morning nursing a Halloween hangover), here's everything we've got on KitKat, the Nexus 5, and anything else you want to know.
A while back, an experimental feature debuted in a Chrome for Android Beta release that seemed pretty innocuous - instead of tapping the overflow menu button to cause the dropdown to appear, you could now press, drag, and release to select an option in the list. From a touch device perspective, it's understandable why such an implementation would be desirable for some users, as it reduces the amount of tapping required for some tasks.
Google is finally paying attention to the phone app in Android 4.4 by adding smart organization of contacts, enhanced search, and a new card-based UI. However, there might be something more dastardly hiding in the dialer code. Google might be preparing to roll out ads of some sort to the Android dialer.
Another bloody update: Paranoid Android has posted a new Gapps package with a few bug fixes. Get it here.
Google might not be sending out those Nexus updates to Android 4.4 as quickly as everyone wanted - at least some of you might have a new Nexus 5 in your hands before the KitKat build for the N4 update is sent out.
One more KitKat feature spotlight for the evening. This time, it's Wi-Fi TDLS. Added in Android 4.4, Wi-Fi TDLS, as Google describes it, is "a seamless way to stream media and other data faster between devices already on the same Wi-Fi network." TDLS, for those that don't know, stands for Tunneled Direct Link Setup.
Essentially, Wi-Fi TDLS allows two devices on the same Wi-Fi network to link directly to one another and share data without burdening the network/router/other devices in the process.
Next in the line of KitKat feature spotlights is the addition of new motion-oriented UX elements meant to give users a dynamic, fluid experience while making it easier for developers to implement high quality animations.
Android 4.4's new transitions framework allows developers to define scenes and transitions. A scene is usually a view hierarchy, while a transition defines how the scene should transform when a user enters or exits it. Developers can use predefined transition types, an auto-transition type, or create custom transitions "that animate the properties that matter most to your app."
That said, developers don't actually have to define scenes to animate UI changes - they can also animate pieces on the fly.
You might remember a couple of weeks ago when Google gave developers a heads up about changes to KitKat that might cause problems for SMS apps. At the time, we knew that this only meant there would be a single app in charge of writing to the database, while all of the others would...well, that part wasn't really defined. Today, one in a series of developer videos gave us a little clarification on what it means to be a default app, and what it means for the rest of them.
Yet another facet of KitKat worth pointing out today is the addition of new security enhancements to the OS. Security is one area that's frequently sensationalized with Android - it seems that every few days a scare story about Android malware creeps onto my Google News page. Google's eliminating security arguments (and possible arguments) one at a time, though, and has made a few key enhancements this time around.
