What stuff specifically? In Version 0.07, we've implemented some toggle options involving MC's solo content and other stuff but they're not yet implemented in itchio's version.
Yup! I've added a fetish filter feature in Version 0.07 (and improved on it in Version 0.08) that's basically a comprehensive list of toggleable content to personalize your playing experience. Any non-hetero content will be listed there and if there are any other future content that you don't wish to see that are in the game, just let me know and I'll make a toggle for it.
