Quick Setup

The first start of Moritz opens the Quick Setup on the splash screen. Change any of it later in Preferences.

Keymap

Moritz (the default), Max or Blender. See Keymaps and Names.

Names

Follow Keymap (the default), Blender, Max or Moritz: whether menus and buttons say Weld or Merge by Distance, Chamfer or Bevel, TurboSmooth or Subdivision Surface.

Everything else (theme, language, select with left or right mouse) is Blender’s own Quick Setup.
