I wanted to make a single thread where everyone can contribute and add modules to serve as a one stop shop for modules until the Magisk Manager gets an xposed-like module downloader. All files are attached in the order that they are introduced.
Busybox Installer - Credits: YasadSharaf for the binaries
The installer detects what architecture (ARM/ARM64, x86/x86_64, MIPS/MIPS64) your device uses and installs the correct busybox binary accordingly.
Better Battery Stats Installer - Credits: @JudgeDread11
The installer systemless-ly installs the Better Battery Stats app.
Screen Density Changer - Credits: @JudgeDread11
The zip changes your screen density systemless-ly, extract the zip to set the value that you would like.
Debloater - Credits: @JudgeDread11
The zip debloats your ROM, he uses for Asus Zenfone 2 could probably be adapted to many more devices.
The simple script mounts the magisk.img to /magisk to allow it to be edited in case a module or script is causing a bootloop.
ViPER4Android Installer - Credits: @topjohnwu edit by me
The installer systemless-ly installs the ViPER4Android app as well as the driver. Detects and supports the x86 V4A driver. It uses the material design version 126.96.36.199 because it is of higher quality than 188.8.131.52. Two zips, one for dark theme and other for light theme.
The installer systemless-ly installs my ad-blocker, which supports updating by running hosts as root in terminal. The updater utilizes a wget port to android. The entire hosts file is 18 MB and has over 600k unique entries. Hosts is located at GitHub.
Liveboot Installer - Credits: @topjohnwu edit by me
The installer systemless-ly installs the LiveBoot app and script. Credits to @topjohnwu for this one I just edited the settings to the way I prefer it. Two zips, one with boot logs and one without both have 60 lines as default.
Credits & Thanks: Mainly @osm0sis for his awesome odds & ends thread that I used as a template and @topjohnwu for Magisk. Also everyone else who has contributed in any way to installer scripts for various mods, I've tried to include your name by the module you contributed to.
Disclaimer: Naturally, you take all the responsibility for what happens to your device when you start messing around with things.
Contributing: Post a reply with your module attached or a link to it with a short description. I'll add it to the OP with credits and a link to your post. Or even post ideas for modules!
