+# Cross Platform Out-GridView
+
+Out-Gridview was a popular command in Windows PowerShell.
+Its dependence on Windows Presentation Foundation API's meant that it didn't make it into PowerShell Core.
+
+> The Out-GridView cmdlet sends the output from a command to a grid view window where the output is displayed in an interactive table.
+
+# Motivation
+
+The feature is a commonly cited reason for not migrating to Powershell Core and its implementation will help further adoption.
+
+# Specification
+
+## cmdlet
+
+The cmdlet will be a modern implementation of [Out-GridView](https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/out-gridview?view=powershell-5.1) and also cross platform supported.
+
+```powershell
+Out-GridView
+   [-InputObject <PSObject>]
+   [-Title <String>]
+   [-PassThru]
+   [<CommonParameters>]
+
+Out-GridView
+   [-InputObject <PSObject>]
+   [-Title <String>]
+   [-Wait]
+   [<CommonParameters>]
+
+Out-GridView
+   [-InputObject <PSObject>]
+   [-Title <String>]
+   [-OutputMode <OutputModeOption>]
+   [<CommonParameters>]
+```
+
+## GUI
+
+The GUI will be implemented on top of [Avalonia UI Framework](https://github.com/AvaloniaUI/Avalonia).
+The project was chosen for its active development, implemented capabilities, modeling of WPF, and cross platform support.
+
+A new feature `Show Script` will be added that will generate an equivalent PowerShell script that represents the filters manually applied to Out-GridView.
+The goal being to enable better automation at scale while also allowing graphical editing of filters.
+
+Wireframe of the new design.
+The wireframe is intended for visual reference, it is **not** a pixel perfect representation.
+The most important part to note is the new layout for filters as opposed to the original "Criteria Panel".

+
+## Module
+
+Out-GridView will be added to the PowerShell Graphical Tools Module Microsoft.PowerShell.GraphicalTools.
+Forming the basis for future cross-platform graphical commands.
+
+## Removed Features
+
+* Search in Column - Better solved by filters
+
+# Alternative Proposals and Considerations
+
+## GUI Frameworks
+
+### Electron
+
+Despite it's popularity as a cross-platform framework, it's slow boot times make it the wrong choice for a command that is frequently used to create confirmation and selection prompts.
+
+### Web
+
+An interesting concept, particularly interesting for the ability to integrate directly into VSCode.
+However, the dependency on having a browser pre-installed makes it less than ideal.
