In this app you can find 3 different bootanimations and Android Nougat sounds and 44+ inedited navbars :)
All the icons are vectors so this works on a wide variety of screen sizes!

0)Legend:
You can choose different type of the same navbar.

DG= DarkGray
LG= LightGray
Mb=Back and recents buttons marshmallow style
Nb= Back and recents buttons Nougat style
Little= Dimension of the Home button standard
Big= Dimension of the Home button like the dimension of Pixel navbar

1) WHAT DO YOU NEED

*YOU NEED A SUBSTRATUM CUSTOM ROM WITH THE LATEST ROOTLESS SUBSTRATUM COMMIT. IF YOU HAVE THIS ROOT IT'S NOT NECESSARY. OTHERWISE YOU NEED ROOT BUT ROM WITH OLD COMMIT MAY GENERATE ERRORS WITH THE THEME. NOT GUARANTEE ANYTHING ON ROM NOT UPDATED

*YOU NEED THE SUBSTRATUM THEME ENGINE APP INSTALLED (https://goo.gl/nM6KCQ)

Substratum is the new theme engine that outclasses Layers. Substratum is divided in 2 type of technologies:

# Substratum Legacy: it is the old layers but it works only with the new app Substratum Theme Engine so unistall the old layers app this is useless.

# Substratum OMS: it is the new technology that have the new quick apply fot themes. it works only with the new app Substratum Theme Engine and you must have a rom that support this new technology!

ATTENTION: Some roms have in Settings in the navbar section an option that can colour your navbar in black and white. So if it is activated your navbar will be without colour. So disable this option reboot and enjoy the navbar!!

NOTICE: For bootanimation you must have Substratum OMS. If you have encrypted phone you can apply the bootanimation but as soon as you do a full reboot it will disappear. you can instead do a soft reboot and it will remain applied.If you have decrypted phone instead bootanimation will always remain applied even after a full reboot. For now this is a limitation due to substratum.

# I HAVE THIS ERROR:
» [com.android.systemui.navbars]: Unfortunately there was an exception trying to create a new APK
» [com.android.systemui.navbars]: Installation of "com.android.systemui.navbars" has failed.

*You must Delete the Substratum App Cache.

# NOUGAT NAVBAR ANIMATION ??
*It is not possible for now make it with Substratum!!! To add animation to navbar i must modify the java code but substratum don't support it.

#HOME BUTTON DOES NOT WORK
*This is a substratum problem. Click on the recent button then on home button to solve.

# NAVBAR AREN'T CHANGING?
*Unistall the previous one first and also make sure that you have busybox installed.
