There is a g-code server command to trigger a wizard whcih you can use from lua:
@wizardCommand name
Executes the wizard command with given name.
Title is only translated for normal gui, not for monitor solution. Items are never translated at the moment. Especially items can contain server expressions making them hard to translate but would eventually be possible. Need to think about this when I optimize translations. Want per module translation files so there is no need to adjust the official version always for changes/additions.
