Lock screen and Home screen
- All Icons on the status bar are now black and white
For example: if in Android 4.3 the color of the battery icon was green, now it's white and so do the other icons. - Full screen cover art in lock screen

New options and features on Settings menu

This section will allow you to customize ringtone/notification separately for Call, Message, Email and S Planner in one place. - No background color option in Power saving menu
I don't know why this option is removed, but in the previous Android version, this option often made users have problem with background colour in Email and Browser app. - Single tap mode
It allows you to dismiss/snooze alarms, calendar events, and timer alerts as well as allows you to answer or reject incoming calls with a single tap. I really like this option, no need to swipe the on-screen icon anymore :D - Show Talkback option in accessibility shortcut
When accessibility shortcut is enabled, you're allowed to display accessibility shortcut or Talkback shortcut or both of them. Well, I think it will help a lot especially if you've managed enable Talkback mode accidentally because Talkback option in accessibility shortcut will make you more easier and faster to get out from this mode, compared when you should struggling swiping the screen using two fingers and select an option using double tap to go to the Talkback option through the Settings menu. - Manage accessibility
It allows you to import/export/update your accessibility settings or share them with other devices via NFC. - Magnification gestures

This option also allows you to temporarily magnify what is under your finger by triple tapping and then holding your finger on the screen. - Colour adjustment
This option will allow you to adjust the colour if the current colour makes you difficult to read your phone's contents. - Notification reminder
It allows you to set intervals to remind you of any unread notifications, so no more missed notifications. - Google subtitles (CC)

Enabling this option will improve device accessibility for users with reduced dexterity by displaying quick menu. Here, you can also set to place quick menu in the right or in the left side of the screen. - Interaction control
When this option is enabled, you're allowed to enable or disable motions and screen time out as well as block certain areas of the screen in an app that is currently opened by pressing and holding Home key and the Volume down key at the same time. - 3x4 keyboard

This option displays apps you've set as default for certain action. It'll make you more faster and easier to switch between apps available that has the same function. - Some options in Developer mode
- New Easter egg animation
If you can see a big "Bean" in Android Jelly Bean, now in Android 4.4.2 Kitkat you can see the Big "K" and "his friends" in your screen as its Easter egg animation. I love this one :) But, when I see the animation, it's like I'm seeing a Windows Phone interface :D
New options and features in Apps menu and in the apps

Now you're only allowed either to uninstall third-party apps or disabled stock apps. - Show disabled apps in Apps menu
It allows you to display all disabled apps quickly from the Apps menu. - Hidden items/Show hidden items in Gallery app
While you're viewing an album, you can hide single or multiple items (photos or videos). This of course will much more easier than if you should rename the file name through My Files app to hide them. When you've had hidden items, you can also show them all using this options. - Quick font size option in Messaging app
