Tabs

To create tabs, place this right after the Window or somewhere above the buttons.

local Tabs = {
    Main = Window:AddTab({ Title = "Main", Icon = "" }),
    Settings = Window:AddTab({ Title = "Settings", Icon = "settings" })
}

Other Functions

This stuff needs more information added to it and it will probably not work either way.

The variable is this.

local TabModule = {
	Window = nil,
	Tabs = {},
	Containers = {},
	SelectedTab = 0,
	TabCount = 0,
}

Select Tab

You can probably select tabs using this function too.

TabModule:SelectTab(Tab)

Create New Tab

To create a new tab, use this.

TabModule:New(Title, Icon, Parent)

Unknown Functions

Get Position

I would say this gets the current position of the tab, but I'm unsure.

TabModule:GetCurrentTabPos()

Set Tab's Window

I don't know what this does. It sets the TabModule.Window to the Window.

TabModule:Init(Window)
