does repl have offline mode or something like that?
An answer that this is an online IDE is insufficient. I have just tried what repl.it does when you go offline. I understand that it doesn't try to work for the user but I don't understand why does it work against the user. Hiding the code that I already had in my browser looks entirely unnecessary to me.
This should be a feature, at least you should be able to type online. For example, in gitlab's online IDE, once you enter the integrated IDE (Yeah, it's more like a text editor cuz there's no autocomplete, intellisense, etc, but still you can edit), you can still open files offline, modify files offline, etc, and commit your changes once you go online. THis is all done through their website (go on gitlab and try out their web IDE, it works online)
