Quite a few people tend to believe that toolbox is a security mechanism to run untrusted software in a container. This is not really true, as toolbox containers can access all files in the user's home directory and thus cause havoc.

Describe the solution you'd like
Make it more explicit in the project documentation that a toolbox can access all private files of a user and thus does not protect against malicious software. I know that it is written that toolbox provides "access to the user's home directory", but I think it would be good to explicitly spell out that this means that malicious software inside a toolbox can steal, encrypt and delete all your personal data, just like malicious software outside a toolbox.

Describe alternatives you've considered
One could argue that it should be obvious that toolbox does not protect against malicious software, but I think it would be better to explicitly warn about that.
