- You will now get an error if an item/message/function/generator/particle/sound with duplicate name exists. Only the first will work.

- Fixed a bug in the multi-message editor which would break if you exited from the message creation

- Improved the multi-message editor buttons, it now uses as title the message/title/text from the underlying message.

- Changed position/design of some buttons

- The title in the bossbar editor if not set will now show 'none' like other message editors

- Removed main_menu buttons from editors and first level menus, to avoid confusion there will only be the 'back & save' button. Also pressing 'esc' will have the same behavior.
