I decompiled the launcher APK. I may be blind... I can't seem to find the layout.xml file. Any help. lol

res/layout/fragment_launcher.xml for the main launcher section and res/layout/fragment_drawer.xml for the app drawer

Great launcher BTW. Any chance you could add the ability to pick the background color of apps that have been set as favorite? Or the ability to create custom app icons?

that could be done because if you notice there is a circular reveal when launching that app that uses the app's color but adding that will make that circular reveal useless (because you couldn't see it) and, moreover, the background of the favourite app would merge with the main background (the circular reveal is a feature of API >= 20 like the banner below, so if you tried it on a non LP device you can't see it)
Custom app icons for where? The drawer? I will add to the todo list the ability to install an icon pack zip file structured in a specific way.

Edit:
Just a thought... When an app is set as favorite, it's displayed on the homescreen as a large rectangular icon. Is there any chance you could get your launcher to check favorited apps for android tv compatibility? If so, a better icon could be displayed. I believe android tv apps only require an argument and an ic_banner.png to be considered leanback compatible. You would just need your launcher to look for the ic_banner.png.

I'm not sure if this is possible. I figure it can't hurt to ask.

it's already like this, and the very same reason why they are set as rectangles (but I'm a fan of Windows' tiles to be honest), every app is probed for a banner, this API though is available only starting from LP so if you tried it on a device running, let's say, Kitkat, that API is not available and the function to get a banner won't be used.
If you take a loot at my video you will see that YouTube and WeUpdate are shown as a banner.
