Add a debug mode for project mode and other languages

It would be cool to have a type of repl where the code is public, but the only way to view it would be to have the url. Introducing unlisted repls. Unlisted repls should: (a) be hidden from your profile (b) act exactly like a public repl except for (a) This would be good for repls that contain partially sensitive info that should only be able to be seen by trusted people. Taking from the previous part, having password-protect repls would be cool: repls that appear on a profile with a key next to it. Clicking on it will take the user to the repl with a blur on top saying `Please enter password to continue`. Please upvote to let the mods know!

So I was hoping we could get a game engine similar to unity and unreal engine. I really like working with on replit and a game engine could really make it better

I *really* *really* want to be able to supply images to students in my online html/css/js classroom. This is a fairly big stumbling block to being able to transfer my lesson activities on to repl.it as a new classroom platform.

Please Let us know what you think and how we can make My Repls dashboard better

So when you make a multiplayer project and you decide to post it, it is normally a question of who should post it. Now I think that is would be good if when posting, if it is a multiplayer repl then you can 'invite' someone to your post and they get all the same things that you do in regards with that post (notifications when someone comments, can edit the post, get cycles from upvotes) Just a suggestion! :)

Hi, so like you added the tabs for files which is cool and I think that it would be a good option to have if all your files would start in the tabs and have the file side bar thing hidden when you open your repl. This then means that i don't have to ctrl+click all my files when i open my repl so that i can navigate between files and also have a wider editor so that i can see my long lines better. So in conclusion, the suggestion is to have an option to have the files start like the image below when you open the repl Thanks for making repl.it so good btw! : )

There is no C++20. Only C++17.

You should have the option to hide your code so no one can copy it.

Currently, even if you select dark theme in the editor, every time you go back to "my repls" to fork or access an old repl, you are flashed with a bright white UI. It would be nice if the dark theme were a consistent experience site wide if chosen.
