JustCode should not be crating any problems for you team if you are the only one using it.
The only file that it creates inside the solution folder is for the shared settings. Its created in the folder where the sln file is located. This file is usually checked-in a source control reporistory so any team members can get its latest version and share the code style across the whole team. If you don't want to use this feature you just don't create shared settings file. If you never do a JustCode->Options->Options sharing->Create solution options you will never have this file created on the file system. Even if you do create solution options, you don't publish it to the source control system you are using.
