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! : )
