This is a follow-up to my System UI mod for the international 6T. This one, however, doesn't require a modded SystemUI.apk and should work on all OOS versions. This version depends on RROs to change the icons and such, so a reboot is usually needed every time something is changed. This also means that it will last through system updates, and is much easier to uninstall.
Standard disclaimers apply: I'm not responsible if this messes something up.
More screenshots are available on the XDA Labs listing.
I've made some changes and tested it on Android 10, and I haven't run into any crashes or issues. If there is a crash, I'll need an actual log or at least steps to reproduce.
