re-position already open window to primary monitor on right side
PS C:\> Open-Webbrowser -Monitor 0 -right
 
re-position already open window to secondary monitor, full screen
PS C:\> Open-Webbrowser -Monitor 0
 
re-position already open window to secondary monitor, left top
PS C:\> Open-Webbrowser -Monitor 0 -Left -Top

.NOTES
Requires the Windows 10+ Operating System
 
This cmdlet was mend to be used, interactively.
It performs some strange tricks to position windows, including invoking alt-tab keystrokes.
It's best not to touch the keyboard or mouse, while it is doing that.
 
For fast launches of multple urls:
SET : -Monitor -1
AND : DO NOT use any of these switches: -X, -Y, -Left, -Right, -Top, -Bottom or -RestoreFocus
 
For browsers that are not installed on the system, no actions may be performed or errors occur - at all.

.SYNOPSIS
Runs one or more scripts inside a selected webbrowser tab.
 
.DESCRIPTION
Runs one or more scripts inside a selected webbrowser tab.
You can access 'data' object from within javascript, to synchronize data between PowerShell and the Webbrowser
 
.Parameter Scripts
A string containing javascript, a url or a file reference to a javascript file
 
.Parameter Inspect
Will cause the developer tools of the webbrowser to break, before executing the scripts, allowing you to debug it
 
.Parameter AsJob
Will execute the evaluation as a new background job.
 
.EXAMPLE
PS C:\>
 
Invoke-WebbrowserEvaluation "document.title = 'hello world'"
.EXAMPLE
PS C:\>
 
# Synchronizing data
Select-WebbrowserTab -Force;
$Global:Data = @{ files= (Get-ChildItem *.* -file | % FullName)};
 
[int] $number = Invoke-WebbrowserEvaluation "
 
    document.body.innerHTML = JSON.stringify(data.files);
    data.title = document.title;
    return 123;
";
 
Write-Host "
    Document title : $($Global:Data.title)
    return value : $Number
";
.EXAMPLE
PS C:\>
 
# Support for promises
Select-WebbrowserTab -Force;
Invoke-WebbrowserEvaluation "
    let myList = [];
    return new Promise((resolve) => {
        let i = 0;
        let a = setInterval(() => {
