I'm definitely most excited for v5
I'd love to see a way for screenshots and saves to be uploaded directly through blockland, rather than using a filesharing site. But I want more than just props that would be put in a general database. Let's say I have a build, and I want to collab on it with a friend. There should be a way to send him the file through rtb. Similar things for screenshots, it would be pretty cool to say "come to my server bro, got something cool to show you" and then send a quick screenshot of it
