That aside, I think it specializes OBS in a way that is too specific for OBS, which tries to be more generic. I think they both have their place, but personally I use OBS for recording videos and SLOBS adds no value for me.

I didn't know about slobs, but the idea of a "theme store" maybe would be something worth to explore on obs, It actually could be a revenue stream, just like wordpress, where the core is open source but you have several theme stores.
