Classic Menus plugin
This plugin makes you able to use the old Maniaplanet menus instead of the modern UI in Trackmania (2020) as well as TrackMania Turbo.
The plugin is accessible via the Openplanet menu (Menu -> Scripts -> Utilities -> Classic Menu). You can access the old-fashioned local play and editor menus this way, however, in Trackmania the online play menu is currently unavailable. From the editor menu track editor, replay editor and skin editor are accessible and fully working. Additionally title tools are avaliable from the classic editor menu, however, the various tools there might crash your game - proceed with caution there. From the local play menu you can play single tracks or launch a server in the local network.
