One thing that would be really helpful is being able to see the replay of your most recent run even if it isn't a PR. Sometimes I get a crazy shortcut and want to show my friends but don't have any video to send :/ I'm not asking for a replay code system (obvious cheating problems associated), just for a way to watch back like a normal replay so I can record it with my phone 😅. Also, I don't know how the framework for map/leaderboard database works but I think it would be really cool if I could click on somebody's profile and see all of their times on their played maps, and maybe even a list maps they have created. I know that the current system doesn't even support searching for maps that you have not explicitly imported already, so this suggestion may not be viable. I'm just putting it out there. Thanks! :)
I want to implement a feature where you can export replays(even non-finished replays) as an code similar to track codes, which you can then send to your friends for them to watch.
As for seeing someone else's times, it might be possible, but if you'd like to see the position on the leaderboard as well it would put quite a lot of pressure on the leaderboard servers. We'll see!
