Proxies is a thing that i really dont know that we can do in Roblox, there are other things that most of devs probably don't know that exists?

I recently discovered the proxies existence and I want to know. What other cool things we can do in roblox like add a proxy? I really want to know.

What you’re asking is pretty vague! Are you just looking for cool things to learn about and use in Roblox?
