Hello Codeforces,
I have been working on an app to download the source code of submissions with verdict Accepted from Codeforces.
Currently the app continues in development and any suggestion is received :P.
The name of app is get-submissions:
To install
# npm install -g get-submissions
To use
$ get-submissions -h <handle> -c <count> -d <directory>
