This page provides links to additional PowerShell ISE tools you can download and add into PowerShell ISE.
Most ISE Add-ons interact and leverage the PowerShell ISE Add-on Model ($PSIse). For more information on the ISE Object Model see: The Windows PowerShell ISE Scripting Object Model at https://docs.microsoft.com/en-us/powershell/scripting/core-powershell/ise/the-windows-powershell-ise-scripting-object-model?view=powershell-5.1
(NB: requires WPK and PowerShellPack modules!)
