It is, and its available for developers to use right now!

Heres an extremely-hacky sample that I made to demonstrate how it works:

-- This code can be pasted into the command bar, but only once. local plugin = plugin or getfenv().PluginManager():CreatePlugin() plugin.Name = "Plugin" plugin.Parent = workspace local pluginMenu = plugin:CreatePluginMenu(math.random(), "Test Menu") pluginMenu.Name = "Test Menu" pluginMenu:AddNewAction("ActionA", "A", "rbxasset://textures/loading/robloxTiltRed.png") pluginMenu:AddNewAction("ActionB", "B", "rbxasset://textures/loading/robloxTilt.png") local subMenu = plugin:CreatePluginMenu(math.random(), "C", "rbxasset://textures/explosion.png") subMenu.Name = "Sub Menu" subMenu:AddNewAction("ActionD", "D", "rbxasset://textures/whiteCircle.png") subMenu:AddNewAction("ActionE", "E", "rbxasset://textures/icon_ROBUX.png") pluginMenu:AddMenu(subMenu) pluginMenu:AddSeparator() pluginMenu:AddNewAction("ActionF", "F", "rbxasset://textures/sparkle.png") local toggle = Instance.new("BoolValue") toggle.Name = "TogglePluginMenu" toggle.Parent = workspace local function onToggled() if toggle.Value then toggle.Value = false local selectedAction = pluginMenu:ShowAsync() if selectedAction then print("Selected Action:", selectedAction.Text, "with ActionId:", selectedAction.ActionId) else print("User did not select an action!") end end end toggle.Changed:Connect(onToggled)

It is also available in Roblox’s new Toolbox. You can right click on an item in the toolbox to view it in a web browser, or copy its AssetId.
