Fruits Basket is amazing and I hope you enjoy it. However, don't expect it to scratch the harem itch. It is more of a love triangle, and I feel like romance isn't much of a focus for many episodes either when the story tends to focus on things like supernatural elements or family trauma instead. I absolutely love Fruits Basket though.
As a side note, I remembered that you mentioned Misuzu from Tomo-chan in your post last week. Well, prepare yourself for Saki Hanajima, the obvious character inspiration for Misuzu. I don't think the ways that the male characters interact with her are as annoying though.
Yeah, I get this. Web UI's/electron apps are taking over everything it seems because it makes things a lot easier to port between platforms in a uniform way. However, I still prefer not having everything be in a browser, I have too many tabs open already!
