2 Film simulation modules

Now Rawtherapee is my principal raw developer. Thinking about how to improve it… I miss one feature that would be very interesting. A second “film simulation” module. It would be great to use one of them for tone, balance, film simulation…, and the second one for some corrections using more technic luts. Or to mix with two sliders two diferent luts…etc. Sorry about my poor english and thanks. What do you think about?
