You'll need sys-tweak to get icons working correctly.
Be sure to update NXThemes Installer to 2.7 it has the new lockscreen IPS patches, it's been stated you HAVE to update via the appstore for it to work correctly, just updating the nro may not work
the icon ratio is 2:3 and fully supports https://github.com/Slluxx/IconGrabber (made by sluxx)
you can also use NX-GIC icons to mass transfer icons as a temporary measure but some icons may not have the right look due to ratio https://sodasoba1.github.io/NSW-Custom-Game-Icons/

Option.szs (has to be manually patched in switchlayouteditor and copied to SDMC:/atmosphere/contents/0100000001000/romfs/lyt with the other szs files)
It's a little more advanced but not impossible.
You'll need switchlayouteditor app
Locate your version of Option.szs: sdmc:/themes/systemData/
Make a copy of Option.szs to your desktop
Open option.szs with switchlayouteditor, then click the load diff patch and apply the diffpatch I made
once it's loaded click save.
Either remove the SD card out of your switch or use hekate UMS mode.
paste the patched option.szs into;
SDMC:/atmosphere/contents/010000000001000/romfs/lyt/
This folder should have other szs files already in there.
Reboot your switch and that's it.



It's taken a lot of work to get it to this level, there are a few things I'm not totally happy with (lockscreen) but I hope to eventually fix those issues when I get some free time.
