- You have the most recent version of the tool - 2.3.0 update.
- The comments in the Atlas.m is already fixed and updated. Thank you for pointing that out.
  Just for information, the comments have no effect on the functionality of the tool.
- Yes, Version Function for the Atlas tool would be very useful and convenient! The ticket for this task is already created and on the path to development.

Thank you again for your priceless comments!
