FAQ:

Q: This homebrew has any impact on games?

A: Negligible, you won't see any difference. Almost everything is done on Core #3, other cores usage is below 0.001%.

Troubleshooting:

Q: When opening Full or Mini mode, overlay is showing that Core #3 usage is at 100% while everything else is showing 0, eventually leading to crash. Why this happens?

A: There are few possible explanations:

1. You're using nifm services connection test patches (in short nifm ctest patches) that are included in various packs. Those patches allow to connect to network that has no internet connection. But they cause nifm to randomly rampage when connected to network. Find any folder in atmosphere/exefs_patches that has in folder name nifm, nfim and/or ctest, delete this folder and restart Switch. If you must use it, only solution is to use this overlay only in airplane mode.
2. You're using some untested custom sysmodule that has no proper thread sleeping implemented. Find out in atmosphere/contents any sysmodule that you don't need, delete it and restart Switch.
3. Your Switch is using sigpatches, is not a primary device, is using linked account, and is connected to network. Delete sigpatches, change your Switch to primary device, unlink account, or disable Wi-Fi.
