Last week it was discovered that longtime favorite home launcher application Nova Launcher would be getting a brand new feature in the latest updated version of the app called Icon Normalization, which is aimed at helping to make the icons in one's app drawer appear more uniform in size comparison. The reason Nova wanted to implement this is because there's now more to icon sizing than just actual size of the icon. The different shapes of each icon and the diversity of their appearance can make it so that even though all icons in an app drawer can be set with Nova to be at 95% of the regular size, some icons will still look bigger than others.
You can see this more noticeably with square icons as they tend to appear a little larger, but thanks to the Icon Normalization feature which is now live, (those who have Nova installed should see the update in their "my apps" section of the Play Store) users can enable this toggle switch and Nova will scale the icons to match in a more uniform manner. This is strictly about visual appearance, so there's nothing to be gained here functionality wise, but that doesn't make it any less important. Having your app drawer look more visually appealing just might make you personally feel better about opening it up day in and day out whether it's for work or personal.
This is what Icon Normalization achieves. A more visually appealing and uniform set of icons so things don't look as out of place as they do without the feature enabled. To tap into Icon Normalization and try it out for yourself, you can reach it from the Nova Settings menu under the "look and feel" section. In addition to the new icon feature, Nova also has some performance enhancements and bug fixes, which is to be expected of generally any app update. There are also some tweaks to get it prepared for when Android 6.0 Marshmallow arrives, which includes a new set of search bar styles which are the Marshmallow and Marshmallow grayscale. Lastly, there's tweaks for Android 6.0 Marshmallow runtime environments, so once Marshmallow hits anyone using Nova launcher should have no issues with continuing to use it.
