Hi Dear Behrooz,
I think it would be grate to consider a description box in HYRCAN. User can write some note or description about the model.
For example, by click on a toolbar icon/menu command, a text box open and the user can read/write text description about model.
Thank you very much.

I put this in the todo list. end of the list thought since there are some more important tasks before it 

Thank you very much
