Xposed GEL Settings, or XGELS, is an Xposed Framework module that aims to make the default Google Now launcher (AKA the Google Experience Launcher) just as customizable as alternatives like Nova. The latest update adds a handful of new options for customization nuts, including tweaks to the icon display on the homescreen and app drawer. You can download XGELS via the Play Store, but you'll need a rooted device and the Xposed Framework (sideload) to make it work.
Version 2.1 adds the ability to display icon labels on those apps placed in the dock on the homepage, which isn't exactly my cup of tea, but apparently someone wanted it. You can also set a space margin for the dock icons, anywhere from below zero up to ten. The changes to the icon dock don't seem to be working on my rooted G Pad 8.3 - changes are inconsistent and the text is cut off.
In the app drawer, you can now add an overscroll animation for moving between tabs. Icons can be enlarged or shrunken, and you can select the number of vertical icon rows, packing more or fewer apps into a visible page. I've changed all the options for the screenshot above, with tiny icons crammed into a single page. Premium users who opt for the $4 upgrade can also add customized folders to the app drawer and move the tabs to the bottom of the screen.
A single setting now changes the page indicator color from white to whatever you like - I chose blue up top just for the contrast. There's also an option not to increase the size of notification number badges when they get to triple digits. A few bug fixes and performance improvements have been thrown in for good measure.
