Curious, cant you just add activatewindow(filemanager) as a custom command in a submenu for File Manager? Or is it because you want File Manager in an Autowidget Group?

I was able to make an AW shortcut for File Manager. It looks like this...
        {
            "label": "File Manager",
            "content": "none",
            "file": {
                "file": "ActivateWindow(filemanager)",
                "filetype": "directory",
                "art": {
                    "icon": "DefaultAddonsSearch.png",
                    "thumb": "special://home/addons/resource.images.skinicons.wide/resources/icons/filemanager.png"
                }
            },
            "color": "white",
            "window": "filemanager",
            "target": "shortcut",
            "id": "search-1634328954.9411094",
            "version": "3.4.2"
        },

But yea, It would be nice if there could be a "Create Custom Shortcut here" option in the context menu while you are inside an AW group like SuperFavorites has. Then be able to add a custom command for the shortcut. Instead of adding a dummy shortcut first and then editing it to work.

That is really useful - I will try it.  I also wonder whether I could incorporate a refresh command using the same idea - so widget 1 would have a static AW shortcut group and widget 2 would have a cycling AW group, then in widget 1 I could have a shortcut which refreshes widget 2.  Must try that tonight!!

Tried it and it will not work.  Sadly had I read some of the early posts from DrInfernoo I would have realised this!  He has already made it clear that the following must be true:

1. target must be "shortcut"

2. path must not be a plugin, library, or Android app path (anything that contains ://)

3. path must contain a set of ( ) (empty or with arguments)

It is the second point which torpedoes my idea, such is life, back to the drawing board
