Here's a list of some things I have working with my currently [keyboard](mm2_home):
* Reactive (sort of) fading while typing, ported from [Velocikey](https://github.com/qmk/qmk_firmware/pull/3754).
* OS Switching, storing to EEPROM
* OS Specific Macros and Shortcuts(WIN+SHIFT+S for Windows and CMD+SHIFT+4 for MacOS)
* Flashing RGB LED on OS change
* Hex Unicode Macros dependent on OS(half works on Windows due to [WinCompose](https://github.com/SamHocevar/wincompose) not functioning properly just yet).
* "Sleep" function activates after 3 minutes (breathing).
* Markdown style macros for surround type __eve__~~ryw~~*her***eee** (apparently only certain places support underline and strikethrough ಠ__ಠ)
