How about adding an amplitude domain split?

[NLesha]

For example, TheZhe TheSplit has an L&S option: "Loud & Soft" mode uses a gate to split audio in the amplitude domain.

Finally I get some time to work on this plugin. The Peak/Steady split is on the amplitude domain, although it uses a dynamic gate. Could you please specify what do you want exactly?

I apologize, I watched the video (https://youtu.be/-RVm9mbbQtA) and did not even try the plugin, I guess the Peak/Steady mode has not yet been implemented. Thank you for clarifying it.
