The files exclude allows you to set true/false values, but it doesn't seem to take them completely into account.

For example, I would like to hide everything except for the scripts folder. You might then assume that this would do this:

{
    "files.exclude":
    {
        "**/*": true,
        "**/Scripts": false
    }
}

It does not do that, it just hides everything. In order to achieve this, you must list every file and directory except for the Scripts directory, and who knows how many directories there are and if a new directory/file gets added you then must edit the list to exclude those.

In the end, their should be a way to hide everything except for xxx.
