In Settings > Problem Archive there is a option to set a Default Programming Language.
If set, it works only when someone is uploading his source code to submit. But most people use the Editor of Toph as they can test their code there too.
But when someone opens the Editor, the language selected there is always Bash.
If it was changed to be the Default Programming Language, that would be a lot better.
Because scrolling down and selecting another language becomes annoying as someone needs to do it repeatedly.
