I'll look into it, thanks for the heads up
During the sessions themselves your domme will ask about your preferences, I want to avoid a situation where it feels like you're the one changing her directly using toggles. This is to increase immersion overall, preferences should be a conversation, not a button. So you're free to refuse her during questions like those as well.
As for planned kinks, I'll post about the newly added ones in the 0.3 update.
