Tips for effectively using Projects?

I really like Claude, and I use it nearly daily. I feel like I'm probably missing out on taking full advantage of it though, because I've never used Projects.

Any tips for using it effectively? Is it better to keep the Projects very niche? Or does it work alright with general/ongoing work?

Also, any other general tips or essential features I'm potentially missing? I'd love to go a bit deeper and not just use the surface level features.
