For now you should still be able to use /np or /NeatPlates for customization, it appears I overlooked this command when renaming the project.

I pushed the fix to the GitHub and I'll make an update to the Twitch client later on today with the fix.

I actually went ahead and released this already in the 6.22b-transition release which is also aimed at making it easier for people to import their old TPC settings.

Thanks the option now visible.
